摘　　要：在开放式网络传输环境下,安全设备间通信需有完备的数据通信协议来保证应用数据安全。提出一种安全通信协议优化方案,对RSSP-I安全通信协议中的所传输数据采用SM4算法进行数据加密,优化开放式网络环境下安全通信协议的分层结构、消息结构和通信交互过程。通过分析论证,针对开放式传输系统存在的所有可能威胁,本安全通信协议实现方法均具备有效的防御、防护技术措施,满足安全设备间数据传输的安全性要求。In an open network transmission environment,communication between security devices requires a complete data communication protocol to ensure the security of application data.This paper proposes an optimization scheme for secure communication protocols,which uses SM4 algorithm to encrypt the data transmitted in the RSSP-I secure communication protocol,and optimizes the layered structure,message structure and communication interaction process of the secure communication protocols in an open network environment.Through analysis and demonstration,this paper shows that this method for implementing secure communication protocols provides effective defense and protective technical measures in response to all possible threats existing in the open transmission system,meeting the security requirements for data transmission between security devices.
