移动通信网中端端认证方案的研究

现有的数字移动通信网中提供移动用户与基地地间的保密通信服务，移动用户的间的端端保密通信在移动通信网中还是一个新问题。本文分析了已有端端认证方案的安全性，提出了一种单钥体制域内端端认证方案和一种单钥／双钥混合体制域间端端认证方案。分析结果结果：新方案不仅安全性很高，而且利用于移动端的实现，也便于网络端的密钥管理。

On End-to-End Authentication Schemes for Portable Communication System

The secure communication service between mobile station and base station has been provided by digital mobile communication networks available.The end to end secure communication between two mobile stations is an new topic. This paper firstly analyzed the security of the end to end authentication schemes available.Then we presented a new intra domain private key end to end authentication scheme and a new inter domain private key/public key hybrid end to end authentication scheme.The analytical results show that the new scheme has higher security,is easy for the mobile to implement the cryptographic algorithms and for the network to manage the keys of all parties.
