中文摘要：

主机或用户的身份在移动环境下的互联网通信以及网络管理中是必不可少的，而身份的真实性更是关系到互联网安全和可信任的重要基础．由于当前在用户和主机身份的研究中存在着诸如不支持全局的一次登录以及真实性不够等方面的不足，本文提出一种用于描述用户和终端设备的通用身份标识符GID，提出基于GID的互联网体系结构IGIDA，并实现了身份真实性认证协议和控制技术，最后还给出了未来基于IGIDA的几种可能的上层应用．

英文摘要：

Identity of users and hosts are necessary in mobile environment and in network management of Interact, and the reality of the identity is even more import in security and trust-worthiness of Internet communication. As there exists some problem in current identity research, such as not supporting global single sign-on and the absence of identity reality, this paper defines a general identifier GID to describe the identity of a user or a endpoint device, and proposes a new Interact architecture based on GID, called IGIDA. This paper also proposes the authenticaion protocol and control mechanism of GID and gives some possible applications in future on IGIDA.
