摘　　要：在全球移动网络(GLOMONET)中,无缝漫游对用户来说是非常可取的。但由于无线网络易被攻击及移动终端具有有限的计算能力,所以对移动用户的安全认证是具有挑战的。近来,一些基于安全认证的智能卡方案被提出。文章的主要贡献是通过对已有方案的改进,提出了一个基于智能卡的身份验证方案。方案采用离散对数函数加密,且只需要在用户、外地代理和家庭代理之间进行4次信息交换。最后证明了方案可以抵制多种攻击。相比已有方案,本方案具有简便和计算量少的优点。Seamless roaming in the global mobility network(GLOMONET)is highly desirable for mobile users,although the proper authentication is challenging.This is because not only are wireless networks susceptible to be attacked,but also mobile terminals have limited computational power.Recently,some authentication schemes with anonymity for the GLOMONET have been proposed.The main contribution of this article is an improvement on the schemes before,it proposes a user authentication scheme based on smart cards,requires between user and two agents are four exchanges of information,and security analysis has proved that the scheme can resist various attacks.Compared with the schemes before,this scheme is simpler and has lower computation.
