A Novel Encryption Algorithm Usted for Power Emergency Communication System

Abstract

With the increasing complexity of access and network structure of smart devices, there are many security threats in smart distribution networks. How to ensure the security of smart distribution network communication has become an important challenge for the safe and stable operation of smart distribution networks in the future. In response to this, this paper proposes an encryption algorithm based on electric emergency communication system. The algorithm uses the random number sequence generated by the two-dimensional mapping to XOR with the plaintext to obtain two ciphertexts. Then, the two ciphertexts are subjected to different scrambling operations, and the two ciphertexts are combined into a matrix according to the parity of the number of loops of the encryption algorithm. The first round of encryption is then completed through column confusion, diagonal interchange, and generation of the next round of keys. Loop through the above steps to get the final encrypted ciphertext. The algorithm is innovative in preventing the attacker from exhausting the key, and the algorithm is simple, the running speed is fast, the encryption is efficient, and the reliability of the data transmission is improved. The algorithm is suitable for application in the electric power emergency communication system to ensure the safe operation of the power communication network, and can effectively improve the security of information transmission and the real-time performance of data transmission in the emergency communication system.
