The data provider is a communication device that provides the target information, and correspondingly, the data acquirer is a communication device that acquires the target information.
The specific communication data is communication data carrying target information, and the specific communication data can be transferred between communication devices which do not access the same 802.11 network. The specific communication data includes a service set identifier, and may be carried in any management frame such as beacon (beacon) frame, Probe Request (Probe Request) frame, or Probe response (Probe response) frame. Of course, in practical applications, the service set identifier may also be carried in other management frames.

The beacon frame is a broadcast frame, and is used for an AP (Access Point) to announce the presence of a network, so that an STA (Station) determines the presence of the network. The AP is an access point of an 802.11 network, such as a hotspot in a WIFI network, and both the AP and the STA may include a communication device.
The Probe Request frame is a broadcast frame for the STA to Probe the surrounding 802.11 network.
The Probe response frame is a unicast frame, and is used for the AP to respond to the Probe Request frame.

The embodiment of the application can be applied to the data communication scene in the 802.11 network, including the communication scene among communication devices in a home or an office. In the prior art, communication equipment needing to communicate has to access the same 802.11 network, which may cause that when some communication equipment does not access the network, communication is difficult to carry out, and therefore, the communication is in an information island state, and the reliability of communication is low. Therefore, to solve this problem, the present application provides a data communication method. In the embodiment of the application, since the transmission of the specific communication data such as the service set identifier does not need to rely on accessing the same 802.11 network, the data provider can add the target information to be transmitted to the specific communication data, and when the data acquirer acquires the specific communication data, the data acquirer can acquire the target information certainly, that is, the data acquirer is provided with the target information through the specific communication data, so that the communication between communication devices which do not access the same 802.11 network is realized, the possibility that the communication devices are in an information island state is reduced, and the reliability of communication is improved.

Since the transmission of specific communication data such as service set identification does not need to rely on accessing the same 802.11 network, the target information is provided to the data acquirer for subsequent passing of the specific communication data, so that communication between communication devices which do not access the same 802.11 network is realized, the possibility that the communication devices are in an information isolated island state is reduced, the reliability of communication is improved, and the target information can be added to the service set identification.
The target information may be encoded according to a predetermined encoding method, and characters in the service set identifier may be replaced by the encoded target information, or the encoded target information may be used as the service set identifier.
The encoding method may be determined in advance, for example, when the target information includes a text, the encoding method may include UTF-8(8-bit Unicode Transformation Format, 8-bit ten thousand code Transformation Format); when the target information includes numbers, the encoding may include Base 64.
UTF-8 is a variable length character encoding method for ten thousand codes.
Base64 is a method of representing binary data based on 64 printable characters.
And step 102, providing the target information to a data acquirer through the specific communication data, so that the data acquirer can connect with the target wireless network or execute the operation instruction.
Since the specific communication data carries the target information, the specific communication data can be provided to the data acquirer, that is, the target information is provided to the data acquirer.
The data provider can enter a hotspot mode, the service set identifier of the hotspot is the specific communication data bearing the target information, and the hotspot can be sensed by the data acquirer in the surrounding environment, so that when the data acquirer senses the hotspot, the hotspot communication data is acquired, and the provided target information can be acquired.
In the embodiment of the application, the data acquirer acquires at least one of the service set identifier of the target wireless network and the password of the target wireless network through the specific communication data, and then can connect to the target wireless network, or acquire the operation instruction, and accordingly can execute the operation instruction.
In the embodiment of the application, the target information can be added into the specific communication data, the specific communication data comprises the service set identifier of the wireless network, and the transmission of the specific communication data such as the service set identifier does not need to depend on accessing the same 802.11 network, so that the target information can be provided for the data acquirer through the specific communication data so that the data acquirer can be connected with the target wireless network, or an operation instruction is executed, thereby realizing the communication between communication devices which do not access the same 802.11 network, reducing the possibility that the communication devices are in an information isolated island state, and improving the reliability of the communication.
Example two
Referring to fig. 2, a flowchart of a data communication method according to a second embodiment of the present application is shown, and the specific steps include:
step 201, obtaining specific communication data of a data provider, wherein the specific communication data comprises a service set identifier of a wireless network.
Since the transmission of the specific communication data such as the service set identifier does not need to rely on accessing the same 802.11 network, in order to subsequently obtain the target information through the specific communication data, the communication between the communication devices which do not access the same 802.11 network is realized, the possibility that the communication devices are in an information isolated island state is reduced, the reliability of communication is improved, and the specific communication data of the data provider can be obtained.
The data acquirer can detect the hot spots in the surrounding environment, and when the hot spots of the data provider are detected, the service set identification of the hot spots can be the specific communication data of the data provider.
Step 202, extracting target information from the specific communication data.

For the extracted target information, if the target information comprises data required for performing service processing, performing service processing according to the data; if the target information includes an operation instruction, the operation instruction may be executed. Of course, in practical application, other corresponding processing operations may also be performed according to target information of other data types.
Step 203, connecting the target wireless network according to the target information, or executing the operation instruction.
In the embodiment of the application, the specific communication data can be acquired and comprise the service set identifier of the wireless network, and the transmission of the specific communication data such as the service set identifier does not need to depend on accessing the same 802.11 network, so that the target information provided by a data provider can be acquired through the specific communication data, and the target wireless network is connected or an operation instruction is executed according to the target information, so that the communication between communication devices which do not access the same 802.11 network is realized, the possibility that the communication devices are in an information isolated island state is reduced, and the reliability of the communication is improved.
EXAMPLE III
Referring to fig. 3, a flowchart of a data communication method according to a third embodiment of the present application is shown, and the specific steps include:
in step 301, a data acquirer provides at least one of a device identifier and key information of the data acquirer.
In this embodiment of the application, optionally, in order to facilitate the data provider to perform identity confirmation on an object performing communication, and further improve reliability of communication, the data acquirer may provide the device identifier of the data acquirer to the data provider, so that the data provider can verify the data acquirer according to the device identifier of the data acquirer.
The device identifier is an identifier of the communication device, and the device identifier may be determined and stored in the communication device when the device is shipped from a factory.
The manner in which the data acquirer provides the device identifier of the data acquirer to the data provider may be the same as the manner in which the data provider provides the target information to the data acquirer, and is not described here any more.
In this embodiment, optionally, in order to reduce the possibility that subsequent target information is acquired by other devices and improve the security of communication, the data acquirer may provide key information, so that the data provider may encrypt the target information subsequently.
The key information is used to generate a key, including an encryption decryption or decryption key in the subsequent. The key information may include a character string of a first preset length (e.g., 8 characters). The key information may be generated by the data acquirer for each communication, or may be generated according to a key information generation rule set in advance and updated at a specific time interval.
The key information generation rule is a rule for generating key information.
The specific time period can be obtained by setting in advance.
The manner in which the data acquirer provides the key information to the data provider may be the same as the manner in which the data provider provides the target information to the data acquirer, and is not described here any more.
In this embodiment of the application, optionally, in order to ensure that the data provider and the data acquirer can accurately acquire the data provided by the other party without both accessing the same 802.11 network, and further improve the reliability of communication, the specific communication data includes the feature code.
The feature code is an identification indicating that specific communication data is for communication between the data provider and the data acquirer. The feature code may comprise a character or a string of characters. Of course, in practical applications, in order to enable the data acquirer to quickly and accurately perform service processing or perform operations corresponding to the data according to the specific communication data, the feature codes may include a plurality of feature codes, and each feature code may correspond to one type of information carried by the specific communication data.
For example, the signature includes ICAT or ADP. Taking the example that the feature code includes ICAT inclusion as an example, if device identification is included in specific communication data, the data structure of the specific communication data may be "ICAT" + "{ deviceId (device identification) }"; if the specific communication data comprises the key information, the data of the specific communication data is a random string of 'ICAT' +8 characters, wherein the random string of 8 characters is the key information; if device identification and key information are included in the particular communication data, the data structure of the particular communication data may be a random string of "ICAT" + "{ deviceId }" +8 characters. The data acquirer can enter a hot spot mode, and the service set identifier of the hot spot is a random string of "ICAT" + "{ deviceId }" +8 characters.
Step 302, a data provider acquires at least one of the device identifier and the key information provided by the data acquirer, authenticates the data acquirer according to the device identifier, and/or encrypts target information according to the key information.
In order to improve the reliability of communication, the data provider can authenticate the data acquirer; in order to improve the security of communication, the target information may be encrypted based on the key information.
In this embodiment of the present application, optionally, in order to improve reliability of communication, the data provider may obtain a device identifier provided by the data acquirer, and confirm that the data acquirer is verified according to the device identifier.
The manner in which the data provider obtains the device identifier provided by the data acquirer may be the same as the manner in which the data acquirer obtains the target information, and is not described here any more.
The data provider can provide the device identifier for the server, the server determines whether the data acquirer is legal or not according to the device identifier, and feeds a determined result back to the data acquirer, if the data acquirer determines that the result is legal, the data acquirer is determined to be verified, otherwise, the data acquirer is determined not to be verified.
The server is configured to provide communication-related services for the data acquirer or the data provider, such as verifying whether the data acquirer is legitimate or not, or acquiring corresponding device information according to the device identifier, where the device information includes a device key and the like that are stored in the communication device together with the device identifier.
The device information is information related to the communication device.
The device key is a key corresponding to the communication device.
The device identifier and the device key may be burned into a flash (flash memory) of the communication device when the communication device leaves a factory.
The server may compare the device identifier with a list of legitimate devices stored in the server, determine that the communication device corresponding to the device identifier is legitimate if the device identifier exists in the list of legitimate devices, and feed back device information of the communication device to the data provider, otherwise determine that the communication device corresponding to the device identifier is illegitimate.
The server can obtain the device identification of the legal communication device in advance and store the device identification into a legal device list.
In another optional embodiment of the present application, in order to improve communication efficiency, the legal device list may also be stored in the data provider, and correspondingly, the data provider may also determine whether the device identifier exists in the local legal device list without verifying the data acquirer through the server, and further verify the data acquirer.
In this embodiment, optionally, in order to encrypt data for communication and improve security of communication, the data provider may obtain key information provided by the data acquirer, and generate an encryption key for the target information according to the key information.
The data provider may provide the key information to the server, and the server generates the encryption key based on the key information according to a key generation rule determined in advance.
The key generation rule is a rule for generating an encryption key from key information.
For example, when the key information is a random string, the corresponding key generation rule may be Base64(HMACMD5 ("random string", { device key })). HMACMD5 is a hashing algorithm.
In another optional embodiment of the present application, in order to improve communication efficiency, the data provider may generate the encryption key based on the key information locally according to a key generation rule agreed with the data acquirer in advance, instead of generating the encryption key through the server. Alternatively, the encryption key may be an encryption key agreed in advance by the data provider and the data acquirer.
In this embodiment, optionally, since the target information may include relatively sensitive information, such as a password, the data provider may perform encryption processing on the target information in order to improve the security of communication.
The target information may be determined in advance, such as by receiving a user submission, etc.
In this embodiment, optionally, in order to further improve the reliability of communication, when the specific communication data includes the feature code, the data provider may obtain the specific communication data carrying the feature code, so as to extract the device identifier and/or the key information from the obtained specific communication data.
For example, if the data acquirer is used as a hotspot and the service set identifier is a random string of "ICAT" + "{ deviceId }" +8 characters, the data provider may obtain the service set identifier of the data acquirer by acquiring a beacon frame sent by the data acquirer, or by sending a ProbeRequest frame and receiving a Probe response frame fed back by the data acquirer, and extract the device identifier and the key information.
Through the operations in steps 301 and 302 described above, the data provider authenticates the data acquirer and/or encrypts the target information. In another optional embodiment of the present application, in order to avoid performing unnecessary operations when the verification fails, if the data provider verifies the data acquirer and encrypts the target information, the target information may be encrypted after the data acquirer is verified. In another optional embodiment of the present application, in order to improve the communication efficiency, the data acquirer may not be authenticated, and the target information may not be encrypted, that is, step 301 and step 302 are optional steps. In another alternative embodiment of the present application, the data acquirer may also authenticate the data provider and/or acquire key information provided by the data provider in a similar manner.
Step 303, the data provider adds the target information to specific communication data, wherein the specific communication data comprises a service set identifier of the wireless network.
For a manner of adding the target information to the specific communication data, reference may be made to the related description in the foregoing, and details are not repeated here.
In this embodiment, optionally, since the length of the specific communication data such as the service set identifier is limited, and the limited length of the specific communication data may be smaller than the target information, in order to ensure that the target information can be added to the specific communication data, and further improve the reliability of communication, the data provider may extract key information from the target information according to the limited length of the specific communication data, and add the key information to the specific communication data.
The limited length of the specific communication data is the maximum load of information carried by the specific communication data, which may be referred to as a payload, for example, the maximum length of the service set identifier may be 32 characters, and if the entire length of the service set identifier is used for carrying the target information, the limited length thereof may be 32 characters.
The key information is the information with the highest importance or the most representative information in the target information.
A number of characters that meet a defined length of specific communication data may be extracted from the target information according to the defined length, and then the extracted characters may be used as key information.
The characters with the number which is in the front of the sequence and is in accordance with the limited length can be extracted according to the sequence of the characters in the target information.
Of course, in practical applications, the key information may be extracted from the target information by other means according to the limited length. For example, the limited length and the target information can be provided to the user, and the characters submitted by the user are received as key information; or, extracting key information from the target information according to the limited length by adopting a method such as machine learning; or extracting the target information to obtain the key information.
For example, the target information includes a target service set identifier, and since the first 9 bits of the service set identifier can be used to accurately identify different hotspots, the first 9 bits of the target service set identifier can be extracted as key information.
In this embodiment, optionally, since the length of the specific communication data such as the service set identifier is limited, and the limited length of the specific communication data may be smaller than the target information, in order to ensure that the target information can be completely provided to the data acquirer, and improve the communication effect and reliability, the number of the specific communication data may be determined according to the length of the target information and the limited length of the specific communication data, and the target information may be split and then added to at least one determined specific communication data, respectively.
The target information may be split according to the limited length of the specific communication data and the length of the target information to obtain a split result with the length less than or equal to the limited length, and the split result is added to the specific communication data respectively.
In this embodiment, optionally, the target information may include more than one piece of data, and in order to facilitate subsequent extraction of the target information from the specific communication data, the specific communication data may also include other data related to the target information, such as whether to encrypt or not, so that, in order to facilitate subsequent accurate extraction of each piece of data included in the specific communication data, and further accurate extraction of the target information, reliability of communication is further improved, and each piece of data in the specific communication data is stored in a set location or carries a corresponding information identifier.
The set position is a position set in the specific communication data for each data.
The information identifier is an identifier corresponding to each data included in the specific communication data, so that information related to the data, such as an encryption identifier, can be used to indicate whether the data is encrypted.
The data that can be included in the specific communication data and the corresponding set position, or the information identifier may be obtained by determining in advance, for example, by receiving a submission from a user. When the data acquisition party acquires the specific communication data, the target information can be extracted according to the set position or the information identifier.
In this embodiment of the application, optionally, in order to ensure that a subsequent data acquirer can accurately extract target information from specific communication data provided by a data provider, and further improve reliability of communication, the information identifier includes at least one of an encryption identifier, a number of frames carrying the target information, a current frame number, a length of the target information, and a position of the target information in the specific communication data.
The number of frames carrying the target information is the number of specific communication data carrying the splitting result of the same target information, namely the number of frames in which the target information is located.
The current frame sequence number is the sequence number of the current frame in the frame carrying the target information.
The length of the target information is the number of characters included in the target information.
In this embodiment of the application, optionally, in order to ensure that the subsequent data acquirer can accurately extract the target information from the specific communication data provided by the data provider, and further improve the reliability of communication, the data structure of the specific communication data may include a feature code + a protocol frame header + a payload.
The header of the protocol frame may include the information identifier in the foregoing.
Take the example of a service set identification length for a particular communication of data being 32 characters.
A data structure may include a signature ICAT (occupying 0-3 characters, for a total of 4 characters), a protocol header (occupying 4-5 characters, for a total of 2 characters), and a payload (occupying the remaining 6-31 characters, for a total of 26 characters). The header of the protocol frame comprises a flag bit and a data type, and each of the flag bit and the data type occupies one character. The flag bits (bits) 7-bit4 may be all 1, so as to further distinguish the service set identifier carrying the target information from other service set identifiers, avoid the data acquisition party from decoding by mistake, and improve the reliability of communication; the flag bit3 is an encryption flag to indicate whether the payload is encrypted (yes can be indicated by 1, and no can be indicated by 0); bit2-bit0 reserved. The data type is a data type of the target information, for example, the target information includes a target service set identifier and a password of the target service set identifier, and the data type may be 00011111, so that a subsequent data acquirer can accurately process the target information based on the data type, thereby avoiding the data acquirer from decoding by mistake.
For example, if the service set identifier not carrying the target information is asd2046 and the target information is [123456789], the target information is added to the service set identifier not carrying the target information, and the service set identifier carrying the target information is obtained as ICATxxx [123456789 ].
Another data structure may include a feature code ADP (occupying 0-2 characters, for a total of 3 characters), a protocol header (occupying 3-6 characters, for a total of 4 characters), and a payload (occupying the remaining 7-31 characters, for a total of 25 characters). The protocol frame comprises a flag bit, frame sequence number information and sub information length, each of which occupies 1 character, and the service set identifier is a character string ending with a null character, so the protocol frame occupies 4 characters in total. The zone bits bit7-bit3 may be all 1, so as to further distinguish the service set identifier carrying the target information from other service set identifiers; the flag bit2 is used to indicate whether the target information is Chinese-coded (may be 1 to indicate yes, and 0 to indicate no); the flag bit1 is used for indicating whether the target information is encrypted; bit0 is reserved. The frame number information bit7-bit4 is the current frame number, and bit3-bit0 are the total number of frames, that is, the number of specific communication data including the split result of the target information. The sub information length is the sub information length included in the target information, so that a subsequent data acquirer can acquire each sub information from the target information. For example, when the target information includes the target service set identifier and the password of the target service set identifier, the flag bit2 is used to indicate whether the target service set identifier is chinese-encoded, and the flag bit1 is used to indicate whether the password of the target service set identifier is encrypted.
For example, if the service set identifier not carrying the target information is asd2046, and the target information includes the target service set identifier abcdef and the password of the target service set identifier is 123456789 abcdefjk 012345678110qwerty, the target information is added to the service set identifier not carrying the target information, and the service set identifiers carrying the target information are adpxxabcdef 123456789 abcdefghii and adpxxjk 012345678110 qwerty.
Step 304, the data provider provides the target information to the data acquirer through the specific communication data.
For a way that the data provider provides the target information to the data acquirer through the specific communication data, reference may be made to the related description in the foregoing, and details are not repeated here.
In this embodiment of the application, optionally, in order to ensure that target information can be provided to a data acquirer through specific communication data, so as to implement communication between communication devices that do not access the same 802.11 network, reduce the possibility that the communication devices are in an information isolated island state, and improve the reliability of communication, a data provider may start a hotspot mode, and provide the specific communication data as a service set identifier to the data acquirer. That is, as long as the data acquirer can detect the hotspot, the target information provided by the data provider can be acquired.
The data provider may enter the hotspot mode, and use the specific communication data as the service set identifier, including sending out a beacon frame carrying the specific communication data, or respond to the Probe Request frame of the data acquirer through the Probe response frame carrying the specific communication data, thereby providing the specific communication data as the service set identifier to the data acquirer.
In another optional embodiment of the present application, the data acquirer may be in a hotspot mode, the data provider sends out a Probe response frame, where the Probe response frame carries specific communication data, and the data acquirer may acquire the specific communication data by acquiring the Probe response frame.
In this embodiment of the application, optionally, as can be seen from the foregoing, the length of the target information may be longer than the limited length of the specific data, so as to be split into more than one specific communication data, and therefore, in order to ensure that the data acquirer can acquire complete information and improve reliability of communication, when the specific communication data includes a plurality of data, the data provider may start a hot spot mode at intervals of a specific duration, and provide each service set identifier to the data acquirer with each specific communication data as a service set identifier.
The specific time period may be determined in advance, for example, the specific time period may be 3 seconds.
For example, the specific communication data for transmitting the target information includes ADPxxxxabcdef123456789ABCDEFGHI and ADPxxxxJK012345678110 qwertyieop, so that the data provider can control the interface related to the hot spot in the system, enter the hot spot mode, the service set identifier of the hot spot is adpxxabcdef 123456789ABCDEFGHI, re-enter the hot spot mode after 3 seconds, and the service set identifier of the hot spot is ADPxxxxJK012345678110 qwertyiop.
In this embodiment, optionally, in order to ensure that the target information can be provided to the data acquirer by the specific communication data, and improve the reliability of communication, the data provider may periodically enter the hot spot mode, and provide the specific communication data as the service set identifier to the data acquirer.
For example, the specific communication data for transmitting the target information includes ADPxxxxabcdef123456789 abcdefghii and ADPxxxxJK012345678110 qwertyieop. After sequentially taking ADP xxabcdef123456789 abcdefghii and adpxxjk 012345678110 qwertyuop as service set identifiers of hot spots, the data provider may repeat the service set identifiers of hot spots again by sequentially taking ADPxxxx abcdef123456789 abcdefghii and ADPxxxxJK012345678110 qwertyuop as service set identifiers of hot spots at an interval of 3 seconds. The preset times can be determined in advance.
In step 305, the data acquirer acquires specific communication data of the data provider, and extracts the target information from the specific communication data.
For the way of acquiring the specific communication data by the data acquirer and the way of extracting the target information from the specific communication data, reference may be made to the foregoing related description, and details are not repeated here.
In this embodiment, optionally, in order to ensure that target information can be completely acquired and improve communication effect and reliability, the specific communication data includes a frame number and a current frame serial number that carry the target information, and accordingly, a data acquirer may extract the frame number and the current frame serial number that carry the target information from the specific communication data, and determine to continue acquiring the specific communication data from the data provider according to the frame number and the current frame serial number that carry the target information.
The number of frames carrying the target information and the current frame sequence number can be acquired from the flag bits in the specific communication data, whether the acquisition of the specific communication data carrying the target information is completed or not is determined according to the number of frames carrying the target information and the current frame sequence number, if not, the acquisition of the specific communication data from the data provider is continued, and if not, the acquisition of the specific communication data from the data provider is stopped.
For example, obtaining ADP xxxxabcdef123456789ABCDEFGHI from the data provider, obtaining the number of frames carrying the target information from the flag bit as 2, and obtaining the current frame number as 1, continuing to obtain ADPxxxxJK012345678110 qwertyuop from the data obtaining party, at this time, obtaining the number of frames carrying the target information from the flag bit as 2, and obtaining the current frame number as 2, and stopping obtaining when the obtaining is determined to be completed.
In this embodiment, optionally, in order to accurately identify specific communication data in surrounding hotspots, that is, to improve the accuracy of acquiring the specific communication data and further improve the accuracy of acquiring the target information, the data acquirer may acquire a service set identifier of a hotspot in the surrounding environment, and if it is determined that the service set identifier includes a feature code, for example, starts with the feature code, it is determined that the service set identifier is the specific communication data. For the determined specific communication data, the characters at the position of the protocol frame header identified by the service set can be decoded according to Base64, if the characters meet the specification of the protocol frame header, the decoding can be successful, the target information can be extracted, otherwise, the decoding fails, and the target information is not extracted.
For example, if the obtained service set identifier is adpxxabcdef 123456789ABCDEFGHI, and it is determined that the service set identifier includes a feature code ADP, and xxxx is successfully analyzed, target information abcdef123456789ABCDEFGHI carried in the service set identifier may be obtained.
In the embodiment of the application, optionally, each data included in the specific communication data can be accurately extracted, and then the target information is accurately extracted, so that the reliability of communication is further improved, each data in the specific communication data is stored in a set position or carries a corresponding information identifier, and correspondingly, the data acquirer can extract the target information from the specific communication data according to the set position of the specific communication data or the corresponding information identifier.
The target information may be extracted from the specific communication data according to a set position of the target information or a length of the target information.
In this embodiment, optionally, since the target information may include more than one piece of information, in order to ensure that each piece of information can be obtained and improve reliability of communication, the target information includes a plurality of pieces of sub information, and the specific communication data includes a length of at least one piece of sub information; accordingly, the data acquirer may extract the length of the at least one piece of sub information from the specific communication data, and extract the piece of sub information from the target information according to the length of the at least one piece of sub information.
The sub information may be extracted from the payload in the specific communication data according to the length of each sub information, and if other information is included in the payload, the remaining information may be extracted as one word information.
For example, for adpxxabcdef 123456789ABCDEFGHI, if one sub-information length obtained from the flag bit is 6, abcdef is extracted as one sub-information, and the remaining 123456789ABCDEFGHI is extracted as another sub-information.
In this embodiment of the application, optionally, since one piece of target information may be split into more than one piece of specific communication data, in order to ensure that complete target information can be acquired, a data acquirer may splice target information acquired multiple times.
The target information carried in the plurality of specific communication data may be spliced according to the current frame sequence number included in each specific communication data.
For example, two specific communication numbers are obtained, which sequentially include ADPxxxxabcd ef123456789 abcdefghii and ADPxxxxJK012345678110 qwertyieop according to the current frame sequence number, and abcdef123456789 abcdefghii includes sub-information ascdef and sub-information 123456789ABCD efghii, so that 123456789ABCD efghii and JK012345678110 qwertyiop are spliced to obtain 123456789ABCD efghjk 012345678110 qwertyiop.
Step 306, the data acquirer decrypts the target information.
To improve the security of communication, the target information may be encrypted, and thus, the data acquirer may decrypt the target information.
In this embodiment, optionally, in order to improve the security of communication further, the key information may be changed, that is, the encryption key used for encrypting the target information in each communication process may be different, so to ensure that the target information can be decrypted, and improve the security and reliability of communication, the data acquirer may generate the decryption key according to the key information corresponding to the communication this time, and decrypt the target information by using the decryption key.
The key information provided to the data provider in the communication can be acquired, and the decryption key is generated.
The way in which the data acquirer generates the decryption key according to the key information may be the same as the way in which the data provider generates the encryption key according to the key information, and is not described here any more.
In this embodiment, optionally, in order to reduce the possibility of incorrect decryption by the data acquirer, that is, reduce the possibility of decrypting unencrypted target information, and reduce unnecessary operations, thereby improving the efficiency and reliability of acquiring the target information, the specific communication data includes an encryption identifier, and correspondingly, the data acquirer may acquire the encryption identifier from the specific communication data, and decrypt the target information according to the encryption identifier.
Whether the target information is encrypted or not can be determined according to the encryption identifier, if yes, the target information is decrypted, and otherwise, the target information is not decrypted.
In another optional embodiment of the present application, since the data provider encrypts the target information is an optional step, if the target information is not encrypted, the step of decrypting the target information may not be performed, that is, step 306 is an optional step.
And 307, the data acquirer processes according to the target information.
The data acquirer can perform corresponding processing operation according to the data type of the target information.
Wherein, the data acquirer can acquire the data type of the target information from the flag bit of the specific communication data.
In this embodiment of the application, optionally, because a propagation manner of the service set identifier is more reliable than a multicast manner or a manner of forwarding the broadcast packet by the router, in order to improve reliability of network configuration for the communication device, a network may be distributed to the communication device through the service set identifier, where the target information includes the service set identifier of the target wireless network and the password of the target wireless network, and correspondingly, the data acquirer may connect the target wireless network according to at least one of the service set identifier of the target wireless network and the password of the target wireless network.
In this embodiment of the present application, optionally, in order to facilitate that the communication device can control another communication device without accessing the same 802.11 network, the target information includes an operation instruction, and accordingly, the data acquirer may execute the operation instruction.
In the embodiment of the application, firstly, the data provider can add the target information to the specific communication data, and the specific communication data comprises the service set identifier of the wireless network, and as the transfer of the specific communication data such as the service set identifier does not need to rely on accessing the same 802.11 network, the target information can be provided to the data acquirer through the specific communication data, so that the communication between communication devices which do not access the same 802.11 network is realized, the possibility that the communication devices are in an information island state is reduced, and the reliability of the communication is improved.
Secondly, the data acquirer can provide the device identification of the data acquirer to the data provider through specific communication data, so that the data provider can verify the communication object, and the reliability of communication is further improved.
In addition, the data acquirer can provide the key information to the data provider by specifying the communication data, so that the data provider can encrypt the provided target information, and the communication security is improved.
In addition, the data provider can enter a hotspot mode, and the service set identifier of the hotspot is the specific communication data, so that the data acquirer can acquire the target information provided by the data provider as long as the data acquirer can detect the hotspot, thereby ensuring that the data acquirer can communicate without accessing the same 802.11 network and improving the reliability of communication.
In addition, the target information may include a target service set identifier and a password of the target service set identifier, so that as long as the data acquirer can detect the hot spot of the data provider, the data acquirer can connect the target service set identifier according to the target service set identifier and the password of the target service set identifier, and the propagation mode of the service set identifier is more reliable than the multicast mode or the mode of forwarding the broadcast packet by the router, so that the reliability of network configuration is improved.
In addition, the data provider can extract the key information of the target information according to the limited length of the specific communication data, add the key information to the specific communication data, or split and add the target information to at least one specific communication data, so that the target information can be provided for the data acquirer, and the reliability of communication is further improved.
