摘要
门限式密钥共享认证已成为目前MANET的分布式认证技术的热点所在。深入分析了当前主流的几种门限式密钥共享认证方案,通过分析比较各自的优劣特性,得出了一种全新的认证体系。新的方案不仅弥补了原有方案的不完全分布式特性,更通过周期性密钥更新进一步提高了系统安全性。仿真结果表明,该方案具有高效率的性能和较高的安全级别,并具有良好的可扩展性。
Threshold key sharing authentication has become a hot research topic in MANET's distributed authentication techniques, In this paper, in-depth analysis of several prevailing threshold key sharing authentication schemes is made. By analyzing their respective strengths and weaknesses, this paper arrived at a brand new authentication system. The new scheme will not only make up for the non-fully distribution characteristic in those original schemes, but also further enhance the security of the system through periodical update of keys.Simulation results show that the new scheme is highly efficient in performance, of higher security level, and has good expandability.
