由于组播通信提供的高效通信机制有效地节省了网络资源,使得组播通信在MANET中的应用不断加强。该文在分析MANET组播通信中节点安全认证面临的安全威胁和安全需求的基础上,分别从密钥管理机制、入侵检测算法和信誉与合作机制等三个方面介绍节点安全认证的相关研究成果,同时分析了各种方案的优点和缺点,并进行了综合比较。文中阐明了目前组播通信节点安全认证方案设计存在的一些问题,指明了下一步研究方向。
Because of the efficient communication mechanism provided by multicast communication, the network resources are effectively saved, and the application of multicast communication in MANET is continuously strengthened. Based on the analysis of security threats and security requirements faced by node security authentication in MANET multicast communication, this paper introduces the related research results of node security authentication from three aspects: key management mechanism, intrusion detection algorithm and reputation and cooperation mechanism At the same time, the advantages and disadvantages of various schemes were analyzed and a comprehensive comparison was made. In this paper, some problems existing in the design of multicast communication node security authentication scheme are clarified, and the direction of further research is pointed out.
