Research on Data Security Encryption Based on Extracting Evaluation Index from Multiple Angles

Abstract

Abstract In order to solve the problem of low accuracy of ciphertext analysis in traditional power system data encryption methods, this paper presents and designs a power system data encryption method based on multi-angle evaluation index. Firstly, the C/S architecture of security protection is established, and the information node of the management information database is supplemented with the multi-level security management system. Then the 3DES encryption algorithm is introduced to balance the weights of the two factors according to the scaling assignment, to increase the data confidentiality, and the embedded terminal is used to assist decryption. The experimental results show that the decryption result of the design method has a high precision, which verifies the effectiveness of the design method in improving the precision of ciphertext.
