移动通信中的一个重要的安全问题是身份匿名。对于在外地链路的移动用户,基于安全性原因,希望对不可信任的访问域和公用网隐藏其真实身份和防止对其位置移动性进行跟踪。该文对移动IP环境下的身份隐藏和路由问题作了探讨,提出了一种具有匿名特性的动态地址分配策略和路由方法,移动用户的真实身份信息通过匿名和安全的连接传送,保证了端到端的保密性。同时对移动主机和移动网络的实现情况分别进行论述。 An important security issue in mobile communications is identity anonymity. For mobile users on foreign links, for security reasons, it is desirable to hide their true identity from untrusted visited domains and public networks and to prevent their location mobility from being tracked. This paper discusses the issue of identity hiding and routing in mobile IP environment. An anonymous dynamic address assignment strategy and routing method are proposed. The real identity of mobile users is transmitted through anonymous and secure connections, End-to-end confidentiality. At the same time, the implementation of mobile hosts and mobile networks are discussed separately.
