An Encryption Method Based on Power Emergency Communication System

Abstract

An encryption method based on a power emergency communication system is used to ensure safe and efficient transmission of data information in the power emergency communication system. Its technical scheme is that the method first utilizes chaotic mapping to generate two random number sequences R and Q and constructs an r confusion matrix and a q confusion matrix corresponding to the two, and then encrypts the plaintext according to the following steps: a. XOR operation on the key; b. Scrambling operation; c. Combine operation; d. Column confusion; e. Diagonal swap; f. Next round of key generation; g. The present invention uses the key generated by the chaotic map and combines the encryption algorithms of scrambling, combination operation, column confusion and diagonal exchange to generate ciphertext, which has a good encryption effect, not only has good anti-attack and anti-tampering performance, but also improves the The data transmission rate can meet the security and real-time requirements of information transmission at the same time.
