Fig. 1 is a flowchart of an authentication verification method 100 for a load identification module according to an embodiment of the invention. As shown in fig. 1, the authentication and verification method for a load identification module according to the embodiment of the present invention has a complex encryption algorithm, and when an illegal hardware cannot obtain software identification data or a private key, the illegal hardware cannot perform encryption, so that legal network access cannot be performed, and the security coefficient of authentication and verification is increased. In the authentication and verification method 100 for a load identification module according to the embodiment of the present invention, starting from step 101, a verifying party sends a software identifier query message of a query module to a target load identification module in step 101, and receives software identifier data fed back by the target load identification module according to the software identifier query message.
Preferably, the software identification data comprises: software production number, software delivery version number and serial number.
In the invention, the checking party can be a system master station or an electric energy meter, and the checking party initiates a software identification query message for querying the load identification module to the target load identification module and receives software identification data fed back by the target load identification module.
In the present invention, the software identification data includes: the software production number, the software factory version number and the serial number are 16 bits in total. The modules of each legal module manufacturer have unique software production numbers, and unique software identifiers are formed by adding software version numbers and production serial numbers, wherein the software identifiers are shown in table 1.
TABLE 1 software identification composition table
In step 102, the verifier sends a dynamic check code query message of the query module to the target load identification module, and receives a first dynamic check code which is obtained and fed back by the target load identification module through encryption calculation according to the software identification data and the current timestamp data in a preset encryption manner.
In step 103, the verifier performs encryption calculation according to the received software identification data and the current timestamp data in a preset encryption manner to obtain a second dynamic check code.
Preferably, the performing encryption calculation according to the software identification data and the current timestamp data in a preset encryption manner includes:
connecting the software identification data with the current timestamp data to determine plaintext data;
multiplying each byte code in the plaintext data with a byte code of a corresponding byte in the private key respectively according to a byte sequence to obtain first encrypted data;

and if the penultimate bit of the second encrypted data is null, determining that the dynamic check code is 0.
Preferably, wherein the method further comprises:
before authentication and verification, a verifier distributes a private key to a load identification module so that the load identification module receives and stores the private key; the load identification module and the private key are in one-to-one correspondence.
In the invention, the checking party initiates a dynamic check code query message of the query module and receives a first dynamic check code fed back by the target load identification module. The first dynamic check code is obtained by encrypting and calculating the target load identification module according to the software identification data of the target load identification module and the current timestamp data in a preset encryption mode.
Specifically, the process that the target load identification module carries out encryption calculation according to software identification data and current timestamp data of the target load identification module and a preset encryption mode to obtain a first dynamic check code comprises the following steps: connecting the software identification data with the current timestamp data to determine plaintext data; multiplying each byte code in the plaintext data with a byte code of a corresponding byte in the private key respectively according to a byte sequence to obtain first encrypted data; adding each byte code in the first encrypted data to obtain second encrypted data; and taking the last but one bit of the second encrypted data as a dynamic check code obtained through encryption calculation. And if the penultimate bit of the second encrypted data is null, determining that the dynamic check code is 0. In addition, before the authentication and the verification, the verifier distributes the private key to the load identification module so that the load identification module receives and stores the private key; the load identification module and the private key are in one-to-one correspondence.
For example, the software identification of a company's module is: 0001001000000001, the private key is: 1111111111111111, when the current time is 12 months, 21 days 09. The whole calculation flow is shown in table 2.
TABLE 2 dynamic check code calculation process table
Wherein, the partial data in table 1 mean: number of bytes (16 software identifiers, 6 times); software identification + time (0001001000000001+ 122109); a private key (1111111111111111111111); first encrypted data (software identification + time multiplied by the private encryption code corresponding bit); second encrypted data (all first encrypted data results added); dynamic check code (take the second last digit of the second encrypted data, if the second encrypted data <10, then the dynamic check code is 0). The private key is a unique key possessed by each load identification algorithm, is distributed for the verifier, is only public for the verifier and the user, and is unknown to other third parties. The generation of the dynamic check code is divided into 3 steps, including: the first step is as follows: multiplying 22 bytes of data consisting of the software identification of 16 bytes and the time stamp of 6 bytes by corresponding byte bits of the private key of 22 bytes; the second step is that: adding 22 data generated by the first encrypted data to obtain a result; the third step: and taking the ten digits of the second encrypted data as the dynamic check code. Wherein, if the result obtained in the second step is less than 10, the tens number is 0.
Specifically, the table includes a first action of total number of bytes, 16-byte software identifier, 6-byte time, and a second action of 16-byte software identifier 0001001000000001 and 6-byte time 122109, i.e., light green part and blue part, respectively, which will be referred to as identification codes hereinafter. The third behavior is a 16 byte factory private password 1111111111111111111. The first step of encryption is to multiply the 16-byte identifier of the second row by the corresponding bit of the vendor private key of the third row, i.e., the 1 st byte identifier by the 1 st byte private key, until the 16 th byte identifier by the 16 th byte private key, the result is 0001001000000001122109 in the fourth row of the table. The second step of encryption is to sum the 16 byte results obtained in the first step, i.e. the 1 st bit plus the 2 nd bit plus the 3 rd bit until the 16 th bit, to obtain a sum result of 18. The final step of encryption is to take the ten digits of the 10-system sum result of the last step, namely 1 in 18, which is the result of the verification algorithm.
In the invention, the byte check result generated by the load identification module is the first dynamic check code, and the first dynamic check code is replied to the checking party (the system master station or the electric energy meter), so that the checking party (the system master station or the electric energy meter) compares the result with the second dynamic check code calculated by the checking party (the system master station or the electric energy meter) for checking.
The following description is required in the process: the software identification is plaintext and can be read by any equipment; the private key is a cipher text, the device layer stores the unique encryption code, and the verifying party stores all distributed private encryption codes so as to ensure the correct identification of one encryption code; in the interaction process of the detection party, the detection party records the unique software identifier of the hardware while removing the legality of the authentication hardware. Therefore, the legality and uniqueness of the modular combination in the detection system are verified; the time identification can be expanded to 3 months and 30 days in 2021 as 08: 34: 37 can be converted into 20210330083437 to increase the dynamicity and complexity of the encryption code by customizing options of time format, length, number of bits and the like; the calculation method of the first encrypted data and the second encrypted data may also be customized.
In the invention, the verifier carries out encryption calculation according to the received software identification data and the current timestamp data in a preset encryption mode at the same time so as to obtain the second dynamic verification code. Specifically, the manner of acquiring the second dynamic check code is the same as the manner of acquiring the first dynamic check code by the target load identification module, and is not described herein again.
In step 104, the verifier compares the first dynamic verification code with the second dynamic verification code, and determines that the target load identification module passes the authentication verification of validity when the comparison result indicates that the first dynamic verification code is consistent with the second dynamic verification code.
In the invention, when a verifier calculates to obtain a second dynamic check code and receives a first dynamic check code, the first dynamic check code and the second dynamic check code are compared, and when a comparison result indicates that the first dynamic check code and the second dynamic check code are consistent, the target load identification module is determined to pass the legal authentication check. After the dynamic verification method is used, if the target load identification module is determined to be illegal hardware equipment, the illegal hardware equipment cannot carry out normal service communication with a verifier (a system master station or an electric energy meter).
The dynamic verification encryption algorithm performs encryption calculation by combining a plurality of elements such as company private passwords, company manufacturer codes, hardware delivery serial numbers and software version numbers, so that the encryption complexity is extremely high, and illegal hardware cannot perform encryption and cannot perform legal network access under the condition that any one element cannot be known. By the dynamic verification mode, the safety factor of the verification is greatly increased. Making it more difficult to break the password.
