扩充SSL协议实现多媒体安全通信

Extend SSL Protocol to Realize the Multimedia Information's Security Communication

随着多媒体技术和Internet技术的飞速发展,在网络上传播的多媒体信息与日俱增,多媒体通信网中的安全问题也显得越来越重要。文中从多媒体信息自身的特点入手,分析了多媒体对传输网络的特殊要求,简单介绍了SSL协议并分析SSL协议存在的问题。对SSL协议进行扩充,添加进加密速度更快的Blowfish加密算法,以保证多媒体信息在确保安全性的前提下又能满足实时性的要求。

With the development of multimedia technology and Internet technology, the multimedia information transmited in the Internet are so abundant. On the other hand, the problems of multimedia information's security in the network become more and more important. This paper, basis of multimedia information's characteristic, analyzes its special requirement for the transmit network. The paper also gives a presentation of the SSL and analyzes the defect of the SSL, and introduces a method that extend SSL protocol,append the Blowfish algorithms to the SSL to realize the multimedia information's security communication and real time communication.
