Description

Technical Field

[0001] The present invention belongs to a collection device, and particularly relates to a nuclear security data collection device based on domestic cryptographic algorithms. Background Art

[0002] Effectively evaluating nuclear security risks can better strengthen nuclear security work to prevent the occurrence of dangerous events such as nuclear accidents. This evaluation requires accurate collection of nuclear security data to ensure the accuracy and reliability of the evaluation results.

[0003] For nuclear security data, it should have a high security level. During data transmission and collection, such data needs to be encrypted to avoid being damaged during data transfer, resulting in inaccurate data. However, traditional single encryption methods can no longer ensure the security of the data to be protected in the increasingly complex network environment. Therefore, a new encryption method is urgently needed to solve this problem. Summary of the Invention

[0009] A nuclear security data collection device based on domestic cryptographic algorithms as described above, which further includes a trust database,

[0010] Trust database: The trust database stores the types of nuclear security data allowed to be collected; matches the data collected by the collection device with the data types in the trust database; and uses the successfully matched data as the required nuclear security data.

[0017] The present invention has the following beneficial effects compared with the prior art: The nuclear security data collection device based on domestic cryptographic algorithms in this application encrypts nuclear security data based on domestic cryptographic algorithms. Compared with the existing international encryption algorithms, domestic cryptographic algorithms have better security. At the same time, during the data collection process, through data screening, it is ensured that the collected data and the encrypted data are all the required nuclear security data, reducing the workload for the data encryption process. Further, during the encryption process, the national secret processing module adopts multiple encryption methods and combines with the hash algorithm to achieve comprehensive encryption of nuclear security data, improving the reliability of the data encryption result.

[0019] The present invention will be further described and explained below in conjunction with the drawings and specific embodiments.

[0020] In one embodiment, before the national secret processing module encrypts the first ciphertext, the national secret processing module further adds an algorithm data string to the end of the first ciphertext to form a plaintext string. The algorithm data string includes data string one corresponding to the domestic cryptographic algorithm type used for encrypting the first ciphertext and data string two corresponding to the domestic cryptographic algorithm type used for encrypting the second ciphertext. The national secret processing module encrypts the plaintext string using the second domestic cryptographic algorithm to obtain the second ciphertext, and the content of the plaintext string is: First ciphertext + Data string one + Data string two.

[0021] In one embodiment, the national cryptography processing module performs hashing on the first data string and the second data string using a hashing algorithm to obtain a hashing value of the algorithm type, and the content of the plaintext string is the first ciphertext + the hashing value of the algorithm type.

[0022] In one embodiment, the national cryptography processing module is further configured to decrypt data, and the decryption process specifically includes:

[0023] Use the domestic cryptography algorithm in the cryptography library to decrypt the received ciphertext respectively to obtain the decrypted plaintext string;

[0024] Use the hashing algorithm in the cryptography library to decrypt the plaintext string to obtain the decrypted first ciphertext, the decrypted first data string, and the decrypted second data string;

[0025] Match the domestic cryptography algorithm type corresponding to the first data string with the domestic cryptography algorithm used to obtain the decrypted plaintext string. When the match is unsuccessful, determine that the decryption fails, and discard or return the received ciphertext; regard the decrypted first ciphertext, the decrypted first data string, and the decrypted second data string as reliable data, and use the domestic cryptography algorithm corresponding to the decrypted second data string to decrypt the decrypted first ciphertext to obtain the initial plaintext.

[0026] The above-disclosed is only a specific embodiment of the present application, but the present application is not limited thereto. Any change that can be thought of by those skilled in the art should fall within the protection scope of the present application.
