Research on the optimization of communication protocol in network security protocol

Abstract

With the rapid development of communication technology, the optimization of communication protocol, as a new generation of intelligent traffic system technology, has attracted more and more attention, in particular, the communication technology in traffic. In the authentication protocol of this paper, the symmetric cipher algorithm ZUC and the asymmetric cryptographic algorithm RSA are used as the cryptographic algorithms of the protocol. RSA is used to decrypt digital signatures for messages. In the current communication scheme, node communication does not have scalability and communication requirements in different scenarios, and a population key negotiation communication protocol was proposed in this paper. Employing the kana and random key parameters of the nodes in the roadside cell group, 3 communication protocols for group broadcasting, group to vehicle communication, and RSU communication between groups were designed. The results show that the protocol can meet the security requirements of network communication. The results show that the communication protocol in this paper is safe and reliable. At last, the communication efficiency of communication protocol is analyzed using communication overhead and average delay. The proposed protocol is an efficient communication protocol and the scheme is superior to other schemes in terms of communication overhead and average delay.
