| 摘 要： | 分析了3G认证与密钥协商协议(AKA)的过程和特点,指出了存在的缺陷,提出了一种新的AKA 改进方案。该方案实现了移动设备(ME)和拜访位置寄存器(VLR)的相互认证,产生的会话密钥对双方都是公正的；该方法避免了双方必须通过资源有限的无线信道传送自己的公钥证书,几乎不需要可信赖第三方参与；同时解决了网络端信息传输的安全性。并对新方案的安全性进行了形式化分析,证明了该协议具有较强的实用性。

| Abstract: | The shortcomings to 3G Authentication and Key Agreement (AKA) protocol were described through analyzing its procedure and security. An improved scheme of 3G authentication and key agreement protocol was proposed, which achieve authentication of Mobile Equipment (ME) to Visitor Location Register (VLR) and secure transfer of message between VLR to Home Location Register (HLR). The session key established by the protocol was fair for both side of communication without the third party involved. Finally, the formal analysis results of the improved scheme showed its good practicability. |
