摘　　要：在移动通信网中,由于无线通信的开放性,最主要的安全问题基本集中在无线接口上,其中包括实体认证和会话密钥的建立、分配和协商等等.在研究以往移动通信网认证协议的基础上,提出了一种新的认证与密钥建立协议.对该协议的安全性及其性能的分析表明,该协议不仅安全可靠,而且还具有简洁高效、运算量小、适用性强等特点,比较适合在移动环境下实现和使用.For mobile communication networks, the main security troubles including the authentication of entities, establishment, delivery, and negotiation of conversation keys mostly concentrate on the wireless interface duo to its inherent openness. In this paper, we first propose a new AKE protocol on the basis of research on other alike ones, then analyze its security and other performance and finally discusses some correlative issues about the protocol. As the analysis shows that our protocol has not only higher safety, but more suppleness, better efficiency, low operation times, and better applicability, thus being suitable for mobile use.
