摘要: 为了解决移动IP注册过程中的匿名认证问题,提出了一个具有用户匿名性的移动IP注册协议.移动用户通过对家乡代理的身份和新建立的Diffie-Hellman 密钥进行Hash运算,并把该Hash值与移动用户的真实身份进行异或,来构造注册请求消息中的临时身份标识符; 家乡代理把接收到的临时身份标识符和重新计算的Hash值进行异或可以得出移动用户的真实身份;每次注册请求消息中的临时身份标识符都不断变化,从而实现了用户身份的匿名性和位置移动的不可跟踪性.理论分析结果表明,该协议不仅实现了移动实体的认证,而且具有很强的匿名性;与彭华熹、冯登国提出的匿名无线认证协议比较,该协议减少了在移动用户端的运算负荷和时间.

Abstract: In order to address the anonymous authentication problem in mobile IP registration, a mobile IP registration protocol with user anonymity is proposed. To construct its temporary identity (TID) in the registration request message, the mobile node (MN) hashes the home agent (HA)s identity together with a newly established Diffie-Hellman key and performs a bitwise XOR over the MNs real identity and the hashed value. Then HA recalculates the hash value and XORs it with the received TID to derive the MNs true identity. The user anonymity and untractability are achieved in the proposed protocol by the TID, which varies with each registration. Theoretical analysis demonstrates that the proposed protocol accomplishes both strong anonymity and mutual authentication among three mobile IP entities. Compared to the anonymous wireless authentication protocol proposed by Peng et al., the proposed protocol reduces the computation load at the MN.

Key words: mobile IP, user anonymity, registration
