对无线网络移动认证协议的分析与改进
WIRELESS NETWORK MOBILE AUTHENTICATION PROTOCOL ANALYSIS AND IMPROVEMENT
摘要
Abstract
In reference documents [ 5, 6 ] , by exploiting elliptic curve based trust delegation mechanism, an efficient authentication mechanism suitable for wireless mobile devices is presented. In terms of anonymity and secure key update, the weaknesses of the scheme are analyzed. Without imposing extra burdens on HLR (home location network) , VLR (visited location network) or MS (mobile station) , an improved scheme is proposed that strengthens the scheme' s secrecy and the encryption key' s update capability: on the one hand VLR is prohibited from acquiring MS' s identification information, on the other hand MS and VLR can update their session keys even when HLR is offline. The improved scheme preserves efficiency and other merits of the original scheme.关键词
