数字认证技术及应用

Digital authentication technology and application

数字证书就是网络通信中标志通信各方身份信息的一系列数据，可以对通信网络中的数据进行加密传输，保证网络的信息安全。文章首先论述了数字认证技术的基本原理及总体构成，而后具体分析了SSL协议中完成一次握手的过程，最后介绍了数字认证技术的3种应用模式及其在电力系统中的应用实例。由此表明将数字认证技术应用到保护信息安全的重要意义。

Digital certificate is a collection of data to identify the participants in network communication and may encrypt the data during transmission to guarantee network information security. The article first elaborated the digital authentication technology basic principle and the overall infrastructure, and then analyzed the process how a hand shake is completed in the SSL protocol, finally introduced three kinds of application patterns of the digital authentication technology and application examples in the electric power system. We came to the conclusion that it is important to apply digital authentication to achieve information security.
