為了在移動網(wǎng)絡(luò)中運用IP 協(xié)議，因特網(wǎng)工程任務(wù)組（IETF）制定了Mobile IP 協(xié)議。移動IP 技術(shù)給人們帶來極大便利的同時，也造成了許多安全隱患。本文提出一種基于移動IP 外地代理分層結(jié)構(gòu)的注冊方案，該方案對現(xiàn)有外地代理分層結(jié)構(gòu)的注冊方案加以改進(jìn)，使得移動IP快速切換能力得以提高，減少了注冊時延，并提高了移動節(jié)點注冊過程的安全性。

Abstract: Mobile IP is defined by the Internet Engineering Task Force(IETF) in order to make use of IP protocol in mobile network. Mobile IP brings people much convenience but causes many security hidden troubles. A registration scheme based on foreign agent hierarchy of mobile IP is proposed, which improves the current registration scheme, increases the ability of fast handoff, reduces the time delay of authentication and registration, and make the registration of mobile IP more secure.
