Information Encryption Algorithm in Power Network Communication Security Model

With the rapid development of communication technology in power networks, data communications are facing traditional network security risks. The information encryption algorithm is a key part of power network communication security. How to ensure the acquisition of confidential data is one of the key factors for the normal operation of the power grid system. The study of encryption algorithms is of great significance to the power grid communication security. This paper mainly researches the information encryption algorithm in the power grid communication security model. The experimental simulation results in this paper show that for the key pair generation time, the SM2 algorithm can generate a 256-bit key very quickly, which is 130 times faster than the RSA algorithm in generating a 1024-bit key, and the 2048-bit key in comparison 730 times faster. Therefore, under the same security level, the encryption and decryption efficiency of the SM2 algorithm is significantly higher than that of the RSA algorithm, and with the increase of the security strength, the superiority of the SM2 algorithm is more prominent.
