According to the technical scheme, the target background management system can be used for acquiring the equipment information of the target wireless communication terminal, and the equipment information of the target wireless communication terminal can help a user to know the basic condition of the target wireless communication terminal, so that the user can manage the target wireless communication terminal according to the actual condition. Meanwhile, the scheme is simple to operate, can facilitate the user to inquire the equipment information of different wireless communication terminal equipment, and is beneficial to improving the use experience of the user.

Illustratively, before transmitting the request information to the target wireless communication terminal of the plurality of wireless communication terminals in step S110, the method may further include generating initial instruction information in response to an instruction of a user, performing integrity check on the initial instruction information to generate first integrity check information, encapsulating the initial instruction information and the first integrity check information with a first preset message header, and performing encryption processing on the encapsulated information to generate the request information.
In some embodiments, the initial instruction information may be first generated according to an instruction of the user. The initial quality information may include a message ID (MsgID) and a message content (MsgContent). The length of the message and the MD5 Checksum (MD 5 Checksum) may then be calculated to generate the first integrity check information. The initial instruction information and the first integrity check information may then be encapsulated with a first preset message header, which may be set as desired, for example, may be 0X7E. After the encapsulation is completed, the encapsulated information is encrypted to generate the request information. The manner of encryption may include, but is not limited to, encryption using a custom communication protocol and encryption using a particular encryption feature code.
In a specific embodiment, AES 256-bit encryption based on a unique feature code of the terminal device (i.e., the target wireless communication terminal) may be used to perform Key, so as to ensure the security of the transmission process. For example, based on the code of the AES-256-CBC-CTS encryption algorithm, the complementary bit string of PKCS5Padding is modified into a special string, and the first two offset characters of each block of 128bits are modified to become a nonstandard algorithm or a custom algorithm for encryption and decryption of front-end APP and background management software. For another example, the modified custom algorithm may be used for encryption and decryption based on a unique 32-bit hardware feature code HWID.
In another specific embodiment, SSL+TCP 8899 Port Socket communication can be also based, and custom Header 7 bytes and tail 1 checksum byte are added. This helps to further improve data transmission security.
In the scheme of the example, the target background management system can further execute the following operations before executing the operation corresponding to the request information, namely receiving the request information, decrypting the request information, carrying out integrity check on initial instruction information in the decrypted request information to determine the integrity of the initial instruction information, judging whether a message header in the decrypted request information is a first preset message header or not, wherein when the message header in the decrypted request information is the first preset message header and the initial instruction information is complete, the target background management system executes the operation corresponding to the request information.
In a specific embodiment, the target background management system can monitor the read request information through the communication interface, analyze specific request Data through the JSON library function after the APP request information is read, then execute corresponding operations according to the analysis MsgID and MsgContent after the user request Data is checked, generate return information after the operation is executed, and perform integrity check, encapsulation and encryption on the return information to obtain the feedback information. The specific process is similar to the process of carrying out integrity check, encapsulation and encryption on the initial instruction information, and is not repeated. In a specific embodiment, length may be calculated for MsgID and MsgContent of the return information, MD5 CHECKSUM is performed for the Length field and MsgID, msgContent to fill in the tail of the message, and 0X7E field is added to the head of the message, and the return information is obtained after encryption.
In the related art, when a wireless communication terminal is managed, data is generally transmitted in a plaintext transmission manner, so that security is poor, and privacy of a user may be revealed. According to the technical scheme, the initial instruction information is processed in the modes of integrity checking, packaging and encryption processing, so that the integrity of transmitted data can be guaranteed, the data is prevented from being tampered, the safety of data transmission is improved, and privacy leakage of users can be effectively prevented.
Optionally, before generating the initial instruction information in response to an instruction of the user, the method may further include establishing a communication link with the target wireless communication terminal. In a specific embodiment, an ssl+tcp Socket interface may be created and connected to the 8899 port of the target wireless communication terminal. A message handling function interface may also be created that may be used for encapsulation and integrity check operations in subsequent steps.
In some embodiments, after the communication link is established, a hash algorithm of Key can be made based on the unique feature code of the target wireless communication terminal, and an Authentication bidirectional access Authentication can be made by combining an SSL certificate, and the method specifically comprises the following steps:
1) Reading a unique feature code of the equipment terminal, namely attempting to read CPU CHIPID hardware feature codes, attempting to read DDR CHIPID hardware feature codes, attempting to read HARDWARE ID hardware feature codes, attempting to read hardware serial numbers, automatically generating a complement 32-bit random number if the hardware serial numbers are not read or are less than 32 bits, and storing the complement 32-bit random number in a ROM FLASH to serve as a hardware unique feature code HWID to generate encryption SSLKEY;
2) Bidirectional authentication when using self-contained X.509 certificates for access;
3) Receiving SSLKEY sent by the target wireless communication terminal after the two-way authentication negotiation is passed;
4) Utilizing a self-defined decryption algorithm to unlock SSLKEY, reading a unique hardware feature code HWID of an accurate equipment end, and encrypting the HWID again by utilizing the self-defined encryption algorithm to generate SSLKEY to be sent to a target wireless communication terminal;
5) And the target wireless communication terminal is disassembled SSLKEY to be compared with the own 32-bit HWID, and is accepted to be accessed after being consistent, otherwise, the target wireless communication terminal refuses to be accessed.
The method further includes decrypting the feedback information to obtain decrypted feedback information, the decrypted feedback information including the feedback information and a message header, determining whether the message header of the decrypted feedback information is a second preset message header, and performing integrity check on the feedback information to obtain an integrity check result, wherein at least part of the feedback information is displayed when the message header of the decrypted feedback information is the second preset message header and the integrity check result is that the feedback information is complete, and at least part of the feedback information includes the feedback information.
As described above, the target background management system may generate the return information after the operation is performed, and perform integrity check, encapsulation, and encryption on the return information to obtain the feedback information. In some embodiments, the target background management system may perform the operations of integrity checking the return information to generate second integrity check information, encapsulating the return information and the second integrity check information with a second preset message header, and encrypting the encapsulated information to generate feedback information.
Optionally, the step of determining whether the message header of the decrypted feedback information is the second preset message header and the step of performing integrity check on the feedback information may be performed simultaneously or sequentially, which is not limited in this example.
The technical scheme can accurately judge the integrity and the safety of the data through decryption processing, verification of the message header and integrity verification, in other words, the scheme is beneficial to improving the safety of data transmission and protecting the privacy of users.
Illustratively, the step of integrity checking the returned information to obtain an integrity check result is performed when the message header of the decrypted feedback information is a second predetermined message header.
In this exemplary scenario, it may be first determined whether the message header of the decrypted feedback information is a second preset message header, and then the integrity check is performed on the feedback information to obtain an integrity check result. Thus, redundant operation can be avoided, the operation efficiency is improved, and the management efficiency of the wireless communication terminal is further improved.
