[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] Airborne-to-ground communication data is used in specific environments, and the requirements for anti-counterfeiting are gradually increasing. In the existing technology, airborne-to-ground communication data is verified using a single parameter, and it is easy to counterfeit if the parameter is known, resulting in low anti-counterfeiting level of existing airborne-to-ground communication data.

[0017] Furthermore, wireless telemetry and control for rockets can reduce the number of ground-based telemetry and control cables, improving transfer and launch efficiency. During wireless telemetry and control, the security and reliability of wireless commands are paramount. To ensure data security, the correctness and security of data transmitted between the missile and the ground need to be verified, checking for transmission errors or malicious modification during transmission. Traditional verification methods such as CRC have universal and fixed algorithms, posing a risk of data forgery and deception. This invention proposes a hash-based verification method that uses a user-defined, private sparse transformation matrix to prevent data forgery and deception, achieving highly reliable and confidential verification of the correctness and security of communication data.

[0018] According to one embodiment of this disclosure, a method for verifying ground-to-ground communication data based on hash verification is provided, such as... Figures 1 to 4 As shown, the method for verifying ground-to-ground communication data based on hash verification includes:

[0019] Step S110: Obtain the ground-to-ground communication data between the two communication devices;

[0020] Step S120: A binary transformation matrix is ​​bound between the two communication devices, and a key is constructed;

[0021] Step S130: Convert the air-to-ground communication data based on the binary transformation matrix and output the first parameter;

[0022] Step S140: Convert the first parameter based on the hash mapping algorithm and the key, and output the second parameter;

[0023] Step S150: Compare the second parameter with the preset key. If the second parameter and the preset key are equal, then the air-to-ground communication data is accurate data.

[0024] In some embodiments of the present invention, the technical solutions provided involve acquiring ground-to-ground communication data between two communication devices; embedding a binary transformation matrix between the two communication devices and constructing a key; transforming the ground-to-ground communication data based on the binary transformation matrix and outputting a first parameter; transforming the first parameter based on a hash mapping algorithm and outputting a second parameter; comparing the second parameter with the key; and if the second parameter and the key are equal, then the ground-to-ground communication data is accurate data. The ground-to-ground communication data is verified using both the binary transformation matrix and the key, avoiding the use of a single parameter for verification and improving the anti-counterfeiting capability of the ground-to-ground communication data. Furthermore, the hash mapping algorithm transforms the ground-to-ground communication data obtained from the binary transformation matrix to facilitate the comparison between the second parameter and the key.

[0025] These steps are described in detail below.

[0026] As Figures 1 to 1 shown, in step S110, obtain the bouncing communication data between two communication devices.

[0027] The specific steps include: establish a communication connection between the two communication devices and interact; the bouncing communication data is transmitted between the two communication devices; the bouncing communication data is preliminarily verified during the transmission process.

[0028] Among them, through the preliminary verification, the bouncing communication data is verified while being transmitted, and the transmission channel of the bouncing communication data between the two communication devices is ensured to be independent.

[0029] In step S120, bind a binary transformation matrix between the two communication devices and construct a key;

[0030] In step S130, transform the bouncing communication data based on the binary transformation matrix and output a first parameter;

[0031] The specific steps include: bind a binary transformation matrix G0 to one of the communication devices, the dimension of G0 is N×M, where N is greater than M; convert the bouncing communication data into an N1-bit binary sequence, denoted as SEQ1, where N1 < N; convert SEQ1 into a bipolar SEQ2, SEQ2 = (2*SEQ1 - 1); read N1 rows of the check matrix G0 from the bound ROM, denoted as G, the dimension of G0 is N1×M; obtain SEQ3 = SEQ2*G, SEQ3 is a group of M-bit parameters; binaryize SEQ3 through the symbol operation operator sig(·) to obtain SEQ4, SEQ4 is the first parameter; that is, SEQ4 = sig(SEQ3).

[0032] In step S140, transform the first parameter based on the hash mapping algorithm and the key and output a second parameter.

[0033] The specific steps include: input the first parameter into the hash mapping model and perform transformation based on the hash mapping; the transformation result after the hash mapping is combined with the key to form the second parameter.

[0034] Among them, the first parameter is transformed by the hash algorithm through the hash mapping model, and random transformation is performed based on the hash algorithm for subsequent data verification.

[0035] The transformation of the first parameter based on the hash mapping algorithm and the key and the output of the second parameter further include: the second parameter is the check code T, where T = f(SEQ4, KEY), f(·) represents the hash mapping function, and T is the mapping check result of a fixed length.

[0036] like Figures 1 to 1 As shown, in step S150, the second parameter and the preset key are compared. If the second parameter and the preset key are equal, then the air-to-ground communication data is accurate data.

[0037] The specific steps include: comparing the second parameter with the preset key and determining whether the second parameter and the preset key are equal; if the second parameter and the preset key are equal, the air-to-ground communication data is accurate data; if the second parameter and the preset key are not equal, the air-to-ground communication data is erroneous data and is corrected.

[0038] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

[0039] In some embodiments of the present invention, the technical solutions provided involve acquiring ground-to-ground communication data between two communication devices; embedding a binary transformation matrix between the two communication devices and constructing a key; transforming the ground-to-ground communication data based on the binary transformation matrix and outputting a first parameter; transforming the first parameter based on a hash mapping algorithm and outputting a second parameter; comparing the second parameter with the key; and if the second parameter and the key are equal, then the ground-to-ground communication data is accurate data. The ground-to-ground communication data is verified using both the binary transformation matrix and the key, avoiding the use of a single parameter for verification and improving the anti-counterfeiting capability of the ground-to-ground communication data. Furthermore, the hash mapping algorithm transforms the ground-to-ground communication data obtained from the binary transformation matrix to facilitate the comparison between the second parameter and the key.

[0040] like Figure 2 As shown, in one embodiment, the hash-based verification device 200 for ground-to-ground communication data further includes:
