基于IPSec的安全多播研究

The Study of Security Multicast Based on IPSec

随着因特网的发展,多播技术已成为一个新的契机,而多播的安全问题也越来越成为多播技术亟待解决的问题。本文就多播所面临的安全问题进行了分析,重点讨论了多播的组密钥管理协议和源认证方案。在此基础上,对如何将IPSec和多播技术结合起来以实现安全的多播通讯进行了深入研究,并提出了相应的设计方案。

With the development of the Internet, the multicast technology has become a new chance. But the security issues of multicast is becoming the problems to be resolved. In this article, we analyze the security issues of multicast,and put emphasis on the multicast group key management protocols and data sender authentication. Furthermore, we study how to combine IPSec and multicast to realize secure multicast communications, and propose a corresponding design.
