Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Example one
In order to solve the problem that the operation is complex when the screen parameter of the electronic screen is set at present, the embodiment provides a method for quickly setting the screen parameter of the electronic screen by using NFC, so as to quickly and conveniently set the screen parameter of the electronic screen.
Referring to fig. 1, the embodiment provides a method for quickly setting a screen parameter of an electronic screen by using NFC, and the embodiment is explained from an implementation method of an information sending terminal, such as a mobile phone input terminal, an NFC card input terminal, and an intelligent terminal such as a computer input terminal.
The method comprises the following steps:
s1, acquiring screen parameter information needing to be set;
in step S1, it should be noted that, screen parameter information to be set is obtained, where the screen parameter information refers to parameter information of an electronic screen, and for example, when the size of the electronic screen is set, correct screen parameters may need to be set to correctly display in factory shipment or after-sales service, but the set screen parameters are complex and are rarely opened, even if the screen parameters are opened, the operation is complex, and the screen parameters are recovered after an operation error is troublesome.
The screen parameter information in step S1 may be obtained in any form, and may be manually input, and the input form may be network input, USB input, installation-specific application input, or the like. It should also be noted that, the screen parameter information to be set may be obtained by automatic reading, for example, the screen parameter information to be set is pre-stored in the storage device, and if the device needs to set the screen parameter and is triggered, the screen parameter information is automatically read.
S2, adding a random prefix or suffix to the screen parameter information to obtain first information;
s3, carrying out hash encryption on the first information to obtain a first hash value;
s4, storing the first hash value as encryption information into the NFC module;
it should be noted that, steps S2, S3, and S4 are processes of encrypting screen parameter information to obtain encrypted information, and multiple encryption methods may be adopted, where a hash encryption method is used in this scheme to implement encryption processing on the acquired screen parameter information for setting an electronic screen. In practice, technical personnel in the field have technical prejudice in data security of NFC short-distance transmission, and encryption processing of transmission data enables the set data to be safer, so that the external stealing or interference can be prevented, the set screen parameter information is stored in the NFC module after encryption, and the NFC module is used as a storage module at the moment.
It should be noted that, in step S2, adding a random prefix or suffix to the screen parameter information is to salt the information, and the random prefix or suffix added to each screen parameter is different and may adopt different random algorithms.
In step S3, it should be noted that the screen reference information may be obtained by using a hash algorithm, such as MD5, SHA1, SHA2, SHA3, ripemm-160, SM3, or other algorithms.
In step S4, it should be noted that the stored encryption information is the first hash value, and the data to be transmitted is also the first hash value. And the decryption terminal needs to compare and verify the received first hash value with a second hash value stored by the decryption terminal, so as to confirm whether the information is tampered.
The Hash algorithm is adopted and the salt adding processing [1] is carried out, so that different inputs are difficult to generate the same output after Hash operation, even a small difference between the inputs can cause great influence on the output, the input content is difficult to be associated through the output content, the original input content is almost impossible to calculate by reverse calculation of the output, and a huge amount of calculation is required. Therefore, the information can be prevented from being intercepted and tampered by adopting the Hash encryption algorithm, so that the security of the transmission of the screen parameter setting data is ensured.
Further, the hash algorithm is adopted in the embodiment, and actually, only the hash value of the transmitted data is used, so that the efficiency of data transmission can be greatly improved, and the screen parameters can be rapidly replaced and set.
And S5, sending the encrypted information to an NFC module of the electronic screen through the NFC module to analyze the encrypted information to obtain screen parameter information needing to be set.
In the step S5, the encrypted information is sent to the NFC module of the electronic screen through the NFC module to obtain the screen parameter information that needs to be set through analysis, it should be noted that the NFC short-distance communication mode needs the information sending terminal to have the NFC functional module, that is, the party that needs to set the screen parameter information needs to have the NFC functional module.
Furthermore, in practice, the current screen parameter information parameter can be copied for backup in a card swiping manner, and the original parameter information can be swiped back through backup information after the mainboard or software is repaired and replaced after sale. It should be noted that, the card swiping mode is to configure the NFC module to be in the passive mode, and at this time, the NFC module is simulated as a card, and it only passively responds in the radio frequency field emitted by the electronic screen to be read and written with information.
The stored encrypted information containing the screen parameter information is read in a card swiping mode, and the encrypted information is set in a system after being analyzed, so that the technical effect of setting the basic function in the card swiping mode is achieved, at the moment, the NFC module is simulated into a card, and the card only passively responds in a radio frequency field emitted by the electronic screen and is read. And after the read information is decrypted and analyzed, the screen parameters of the electronic screen are set.
NFC is a wireless connection technology that provides easy, secure, and rapid communication, and has features of short distance, high bandwidth, low energy consumption, and the like, compared to RFID. NFC has become compatible with existing contactless smart card technology and has become a formal standard supported by more and more major vendors. Again, NFC is a short-range connection protocol that provides easy, secure, rapid, and automatic communication between various devices. Compared with other connection modes in the wireless world, the NFC is a short-distance and more private communication mode, and when screen parameters of the electronic screen are carried out in the NFC mode, the NFC device is more convenient and quicker than traditional USB, serial ports and other modes, and further reduces the complexity of operation.
In practical application, parameters of the electronic screen are set in a short distance, so that the situation that screen parameter information is stolen and interfered and the like may exist, and therefore the unsafe problems that basic functions cannot be realized after the screen parameter information is set on the electronic screen or the screen parameter information is leaked and the like can be caused.
Example two
In order to solve the problem that the operation is complex when the screen parameters of the electronic screen are set at present, the embodiment describes the method from the electronic screen end by providing a method for quickly setting the screen parameters of the electronic screen by using NFC, and after receiving the encrypted information for implementing the screen parameters of the electronic screen, the method realizes the quick and safe setting of the screen parameters of the electronic screen.
The embodiment provides that by adopting a hash decryption mode, corresponding to the method for encrypting the screen parameter information in the first embodiment, the insecurity problem after the screen parameter information of the electronic screen is stolen can be solved, and the problem that the basic function caused by information interference cannot be realized can be solved.
Referring to fig. 2, the present embodiment provides a method for setting a screen parameter of an electronic screen using NFC quickly, where the method includes the following steps:
s6, receiving the encrypted information sent to the electronic screen through the NFC module of the electronic screen;
in step S6, it should be noted that the manner of obtaining the encrypted information from the encrypted information sent to the electronic screen corresponds to the short-distance transmission manner of sending the encrypted information to the electronic screen by short-distance transmission in step 3 in the first embodiment, an NFC short-distance communication manner is adopted, and the technical and effective effects of the NFC short-distance communication manner are the same as those in the first embodiment, and will not be described in detail.
S7, adding a random prefix or suffix to the screen parameter information to obtain second information, and storing the screen parameter information in a database of the electronic screen end in advance;
s8, performing hash calculation on the second information to obtain a second hash value, and storing the second hash value into a database of the electronic screen end;
s9, comparing the first hash value with the second hash value to obtain screen parameter information needing to be set, wherein the first hash value is obtained through encrypted information received by the NFC module of the electronic screen.
It should be noted that, in steps S7, S8, and S9, the decryption method for decrypting the received encrypted information to obtain the screen parameter information corresponds to steps S2, S3, and S4 in the first embodiment, and multiple encryption methods may be used.
It should be noted that, in step S7, a random prefix or suffix is added to the screen parameter information, and the salt value processing algorithm for salting the information corresponds to the step of step S2 in the embodiment, and the random algorithm should be the same. It should be further noted that all screen parameter information is pre-stored, so in order to save the setting time of parameter verification and improve the efficiency, a random prefix or suffix is added to the screen parameter information, and the salting process may be performed on the information in advance, and then the information is stored in a related manner.
In step S8, it should be noted that the algorithm for calculating the second hash value needs to be the same as the algorithm used in step S3 of the embodiment, and different hash values exist for different parameter settings. It should be further noted that all the second hash values are pre-stored to form a hash table, so in order to save the setting time of parameter verification and improve the efficiency, all the hash values can be pre-calculated to be stored, and when performing verification, table lookup can improve the efficiency.
In step S9, it should be noted that in the first embodiment, the first hash value transmitted is used for comparison and verification of the second hash value obtained by table lookup, so that it is determined which set parameter is, and whether the set parameter has been tampered with or not.
The technical solution of the present embodiment that adopts the hash decryption method corresponds to the first embodiment, and the technical effects produced by the first embodiment are the same as those of the first embodiment, and therefore, a description thereof is omitted.
And S10, setting the parameters of the electronic screen according to the obtained screen parameter information.
In step S10, it should be noted that the screen parameter setting is an electronic screen parameter setting performed by parsing a data packet, where different parsed data packets may perform different function settings, such as size, screen brightness, and the like of the electronic screen, and the electronic screen responds to the data thereof. If the analyzed data packet needs to adjust the screen color brightness to a factory value, the electronic screen automatically adjusts the screen color brightness to the factory value after the analyzed setting data packet is issued.
