基于身份公钥的后三代UMTS安全漫游方案
首发时间:2007-12-24
摘要:提出了一种适合后三代UMTS系统的域间安全漫游管理方案。该方案利用基于身份的公钥体制,将UMTS系统的接入安全要求与移动IP相结合,为移动节点发生域间移动,以及在外地域发生微移动和宏移动提供安全漫游管理。该方案不仅满足UMTS系统移动性管理同AAA的结合,并且能够抵抗伪基站攻击,提供用户匿名性,无需系统进行证书管理及同步维护。

B3G UMTS secure roaming scheme based on ID-based cryptography
Abstract:A secure mobility management scheme for beyond 3G Universal Mobile Telecommunication System (UMTS) is provided in this paper. Mobile IP is combined with USTM secure requirements on the basis of ID-based cryptography. The scheme realizes the cross-domain roaming security and the mobility management within a foreign domain. Compared with other schemes, our scheme decreases the overhead in system management, realizes the resist against false base station attack and user anonymity.
Keywords: secure roaming ID-based cryptography UMTS
