本文基于网络通信安全理论及多层安全结构分析,首先阐述网络通信安全理论,其次研究网络通信的安全结构,其主要内容有两个方面,多层安全结构方案与公开密钥体系,操作人员应结合具体情况进行有效比对,应用虚拟专用网络技术、接层协议安全架构、安全电子邮件,并选取合理的加密方法。 Based on the theory of network communication security and the analysis of multi-layer security architecture, this paper first describes the theory of network communication security and secondly studies the security architecture of network communication. The main contents of this paper are two aspects. The multi-layer security architecture and public key system, Effective combination of specific circumstances, the application of virtual private network technology, layer protocol security architecture, secure e-mail, and select a reasonable method of encryption.
