The following describes methods and apparatuses for setting and processing permissions of a WIFI module according to embodiments of the present application with reference to the accompanying drawings.
Generally, a WIFI module is provided in an intelligent appliance to enable connection of the appliance to an external network. The WIFI module in the existing intelligent household appliance does not usually have a software license, the same WIFI module firmware can be randomly burned onto a plurality of modules for use, and the rights and interests of a WIFI module owner cannot be guaranteed. Alternatively, the first and second electrodes may be,
the WIFI module of the existing intelligent household appliance is provided with a software license. FIG. 1 is a schematic diagram of software license generation and verification according to one embodiment of the present application. As shown in fig. 1:
the software license is generated and burnt to a specific position in the WIFI module according to a physical address (MAC for short) of the WIFI module, and after the WIFI module is powered on, a user reads the software license from the specific position and compares the software license with the physical address of the user to determine whether the WIFI module is normally started. However, such generation of a software license does not have distinction of functional rights, and security is low.
In order to solve the above problems, an embodiment of the present application provides a method for setting permissions of a WIFI module, which generates software licenses with different function permissions and burns the software licenses into the WIFI module to set the permissions of the WIFI module, so that division of the function permissions for a user is achieved, safety of the WIFI module is improved, and applicability is high. The method comprises the following specific steps:
fig. 2 is a flowchart of a method for setting permissions of a WIFI module according to an embodiment of the present application.
As shown in fig. 2, the method for setting the permission of the WIFI module according to the embodiment of the present application includes:
step 110, generating a license character string corresponding to the to-be-processed WIFI module, where the license character string includes: and setting the MAC address of the WIFI module in the MAC address field, and identifying the functions which can be used in the WIFI module in the function permission field.
Specifically, a license character string corresponding to the to-be-processed WIFI module is generated first, and in the generation process, different function fields of the license character string need to be defined.
The license string has many kinds of functional fields, such as a MAC address field, a functional right field, a protocol header field, a license length field, an extended function field, and a check field. One or more of the functional fields may be required depending on the actual application. The following is illustrated in connection with table 1:
table 1 is a schematic table of the functional fields that define the different license strings
Figure BDA0001145377760000051
As shown in table 1: the protocol header field is used to identify the protocol start, for a total of two bytes.
As shown in table 1: the license length field identifies the overall length of the license, one byte.
As shown in table 1: the MAC address field is used for identifying the MAC address of the WIFI module, and before the WIFI module runs, the value of the MAC address field and the consistency of the MAC address of the WIFI module need to be checked, and the total number of the MAC address field and the MAC address of the WIFI module is 6 bytes.
As shown in table 1: the extension field is used for other entitlement management controls for the user's extended software license for a total of N-16 bytes.
As shown in table 1: the verification field is used for verifying the accuracy of the license character string, the value of the verification field is a complementary code obtained after summing all bytes before the software license verification field, and the complementary code is expressed as follows: sum (Byte0+ Byte1+ … … + bytene) +1, one Byte.
As shown in table 1: the function permission field is used for setting the permission level of the software license, and the software can start different functions according to the value of the function permission field, and the total number of the functions is 8 bytes.
It should be noted that the position and length of each function field of the license string can be adjusted and expanded as needed.
The function permission field may include one or more of a distribution network function, a home appliance OTA upgrade function, a cloud platform docking function, a near field discovery function, a wechat direct connection function, and the like.
It can be understood that, if the above functions can be used or prohibited from being used in the WIFI module, the bit corresponding to the function that can be used in the WIFI module may be set to 1 in the functional authority field, and the bit corresponding to the function that is prohibited from being used may be set to 0.
It should be noted that one or two of the above may be set in the WIFI module according to actual application needs.
Taking the function permission field in table 1 as an example, each Bit of 8 bytes (64 bits in total) corresponds to a function. Illustrated in conjunction with table 2 are the following:
Figure BDA0001145377760000061
therefore, the software license authority level can be set according to different functional requirements of different users. The firmware that can guarantee WIFI module production keeps the same set, only need to give different software licenses just to different functional requirements.
And 120, encrypting the license character string by using a preset encryption algorithm to generate a software license, and burning the software license into a specified target area in the WIFI module.
Specifically, in order to further ensure the security of the WIFI module, a preset encryption algorithm needs to be applied to encrypt the license character string to generate the software license.
Among them, there are many kinds of preset encryption algorithms, such as MD5 encryption algorithm, DES encryption algorithm, RSA encryption algorithm, and the like. The settings may be selected as desired. Taking the RSA algorithm as an example of a preset encryption algorithm, RSA-1024 asymmetric encryption (encryption is performed with a private key of an RSA key) is performed on the license string to form a producible software license, and the software license is burned into a specified target area in the WIFI module.
The designated target area can be selected according to actual needs, such as a fixed address in Flash, a fixed address of a specific storage area, and the like.
According to the method for setting the authority of the WIFI module, firstly, a license character string corresponding to the WIFI module to be processed is generated, wherein the license character string comprises: the method comprises the steps of setting the MAC address of the WIFI module in the MAC address field, identifying functions which can be used in the WIFI module in the function permission field, then encrypting a license character string by applying a preset encryption algorithm to generate a software license, and burning the software license into a specified target area in the WIFI module. By generating software licenses with different functional authorities and burning the software licenses into the WIFI module to set the authority of the WIFI module, functional authority division for users is realized, the safety of the WIFI module is improved, and the rights and interests of a WIFI module owner are guaranteed.
Fig. 3 is a flowchart of a processing method of a WIFI module according to one embodiment of the present application.
As shown in fig. 3, a processing method of a WIFI module in an embodiment of the present application includes:
step 210, reading out the encrypted software license burnt in advance from the target area specified in the current WIFI module.
And step 220, decrypting the software license by applying a preset decryption algorithm corresponding to the encryption algorithm to obtain a license character string.
Specifically, when the device is used, the encrypted software license burned in advance is read out from the target area specified in the currently connected WIFI module, and then the license character string is obtained by applying a preset decryption algorithm (for example, decrypting the public key by using the RSA key) corresponding to the encryption algorithm.
It should be noted that, mainly, the encrypted software license pre-burned in the currently connected WIFI module may obtain the license character string through the corresponding decryption algorithm.
The license string may include one or more of a MAC address field, a function right field, a protocol header field, a license length field, an extended function field, and a check field.
It should be noted that, the specific definition of the above field may refer to step 101, and is not described in detail here.
Step 230, comparing the MAC address read from the MAC address field of the license string with the MAC address of the current WIFI module.
And 240, if the MAC addresses of the WIFI module and the MAC address of the WIFI module are consistent, starting the functions which can be used in the WIFI module according to the identification of the function permission field of the license character string, and closing the functions which are forbidden to be used in the WIFI module.
Specifically, the MAC address read from the MAC address field of the acquired license string is compared with the MAC address of the current WIFI module. And when the two are consistent, further processing according to the identification of the function authority field of the license character string. For example, a bit in the function permission field is 1, which corresponds to the wechat and direct connection function, so that the wechat and direct connection function is started. For example, a certain bit in the function permission field is 0, which corresponds to the kyoto cloud, so that the use of the kyoto cloud is prohibited.
It should be noted that when the MAC addresses of the WIFI module and the WIFI module are inconsistent, it is determined that the current WIFI module is illegally restarted.
In order to ensure the reliability of the acquired license character string, a protocol header field in the license character string can be checked before the MAC address read from the MAC address field of the license character string is compared with the MAC address of the current WIFI module, the integrity of the license character string is checked according to a check field in the license character string, and when the license character string is complete, the MAC address is further checked. The safety of the WIFI module is further improved.
According to the processing method of the WIFI module, firstly, an encrypted software license burnt in advance is read out from a target area appointed in a current WIFI module, then, a preset decryption algorithm corresponding to the encryption algorithm is applied to decrypt the software license, a license character string is obtained, then, an MAC address read from an MAC address field of the license character string is compared with an MAC address of the current WIFI module, and finally, when the MAC addresses of the two are consistent, a function which can be used in the WIFI module is started according to an identification of a function authority field of the license character string, and a function which is forbidden to be used in the WIFI module is closed. Therefore, the function permission of the user can be opened or closed, the safety of the WIFI module is further improved, and the rights and interests of the owner of the WIFI module are guaranteed.
