【摘要】 多播的安全问题不单单只包括多播分组数据的安全性。利用多播的安全隐患发起拒绝服务攻击现象在网络环境中越来越多。多播的安全隐患根源是多播的开放组模式。通过研究现有多播控制协议的安全问题,总结恶意攻击的特性并提出一种多播安全控制的解决方案,用于缓解多播安全漏洞对多播传输造成的危害。该方案可以使网络管理员按照网络应用的具体要求有效的控制和管理多播分组。并且在Linux平台下实现了该方案。更多还原

【Abstract】 The security of multicast is not only composed of security of multicast data. Denial of Service attack based on security vulnerabilities of multicast protocols occures more and more frequently in network environment. The open group multicast model leads to security vulnerabilities. By investigating the security vulnerabilities of the existing multicast protocols, this paper summarizes the characteristics of malicious attacks and proposes a multicast security control solution to alleviate the security vulnerabilities in multicast transmission. The solution is implemented in the Linux operating system.Network administrator can control and manage multicast packets effectively according to specific network applications with the solution.更多还原
