摘要：

针对现有演进分组系统认证与密钥协商机制中认证向量组长度K值选取算法的不足,在消息通信量的基础上,加入比特通信量这一衡量因子,引入2种浪费率作为评价指标和设计折中选取原则,提出了一种基于认证次数动态选取认证向量组长度K的算法. 仿真结果表明,提出的选取算法不仅解决了K值不唯一问题,还有效降低了认证过程的消息通信量和比特通信量.

关键词: 认证与密钥协商, 消息通信量, 比特通信量, 认证向量组

Abstract:

Aiming at overcoming the shortages of the current proposed K-selection algorithm for evolved packet system (EPS) authentication and key agreement, an automatic K-selection algorithm on the base of authentication numbers was put forward. Based on message exchange traffic, this algorithm adds the bit exchange traffic as measures and introduces the two wastage rate of authentication vectors. Simulation shows that the proposed algorithm effectively reduces bit exchange traffic and message exchange traffic, and gains an unique K value.

Key words: authentication and key agreement, message exchange traffic, bit exchange traffic, authentication vector array
