A Secure Transmission Method of Network Communication Data Based on Symmetric Key Encryption Algorithm

Abstract

In order to solve the problems of low transmission efficiency and high transmission bit error rate in traditional transmission methods, a new secure transmission method of network communication data is designed based on symmetric key encryption algorithm. Based on the analysis of the security key theory, the agentless key publishing protocol is adopted to control the access of network communication data, so as to construct the ciphertext protocol. Then the key construction in the encryption process is completed by bilinear mapping method. On this basis, the encryption and decryption algorithm, dynamic key generation module and Shared key update module are combined to realize the secure transmission of network communication data. The experimental results show that the bit error rate of this method was kept below 1%, the time of transmission was below 80 s, and the VIM value exceeded 0.1, indicating that this method has the advantages of high data transmission efficiency, low bit error rate and safer transmission process.
