Abstract
Undoubtedly,GSM is the most important standard of the worldwide wireless communication in recent periods.The authentication protocol is the main component of the GSM architecture.However,there are several drawbacks found in the existing authentication protocol of GSM,such as bandwidth consumption between VLR and HLR,storage overhead in VLR,and the property that VLR cannot be authenticated.Nowadays,many authentication protocols are proposed to improve these drawbacks.Among them,Hwang et al’s protocol [C.C.Lee,M.S.Hwang,W.P.Yang,Extension of authentication protocol for GSM,IEE Proceedings of Communication,150(2) (2003) 91–95 [1]],proposed in 2003,can solve the above drawbacks.However,authenticating VLR is just executed at the first time,which MS joins into a new visiting VLR to ask for communication service.In this paper,we propose an improvement to modify Hwang et al’s protocol such that mutual authentication between VLR and MS is ensured at anytime while MS sends an authentication request.In addition,we also propose a brand-new authentication protocol which can not only solve those drawbacks but also make the authentication more efficient.q 2005 Elsevier B.V.All rights reserved.

毫无疑问,GSM是在全球无线通讯近期最重要的标准.身份验证协议是在GSM架构的主要组成部分.但是,也有从事GSM,现有的认证协议,如发现之间的VLR与HLR,存储在VLR开销,并认为无法验证的VLR财产带宽消耗几个缺点.如今,许多认证协议,提出了改善这些缺点.其中,黄禹锡等人的协议[观光开发李咪黄禹锡,W.P.杨,认证的GSM,电机工程师学会通信,诉讼协议扩展150（2）（2003）91-95 [1]],在2003年提出,可以解决上述弊端.然而,仅仅是执行认证的VLR在第一时间,微软将加入一个新的访问的VLR,要求通信服务.在本文中,我们提出了一个改进,修改黄禹锡等人的协议,这样的VLR和MS之间的相互认证是保证在任何时候,而微软发送一个验证请求.此外,我们还提出了一个全新的身份验证协议,不仅能解决这些弊端,而且使验证更有效.q 2005年爱思唯尔B.诉保留所有权利.
