摘要
安全问题一直是多播技术发展中一个亟待解决的问题,而在所有的安全问题中,安全多播准入控制是研究的焦点。研究了国内外现有的典型多播准入控制方案,对它们的优缺点进行了分析和比较研究。结合各种多播准入控制方案的优点,给出了一个基于IGMP协议的安全多播准入控制方案。实验表明该安全多播准入控制方案具有安全性高、稳定性好、扩展性好、易于迁移到IPv6环境和便于部署等特点,有较高的实际应用价值。
Multicast security is a urgent problem to be solved in multicast technical development all the time, of which access control is the core problem. This paper detailedly analyzes the existing typical multicast access control schemes both at home and abroad, then analyses and compares to their advantages and disadvantages. Combining the advantages of existing different multicast access control schemes, it provides a scheme of secure multicast access control based on IGMP. The experiment results prove that this multicast access control scheme not only keeps the high security and stability, but also easy to move to IPv6 environment and easy to deploy, has good extensibility. In a word, this scheme has higher actual using value.
