现有GSM无线通信系统中应用最为广泛的是COMP128-1算法,其安全漏洞最早是由伯克利大学的一个研究小组公布的.本文主要分析了现有的针对COMP128-1算法漏洞的一些攻击及防护手段,提出了基于相邻鉴权矢量的相似度分析的新的安全防护手段,以有效识别对COMP128-1漏洞的攻击鉴权行为,从而有效抵抗这些攻击手段,保护KI不被破解.

COMP128-1 is the most widely-used algorithm in the GSM telecom system,but the leak in it has been found by a R&D team of Berkeley University at 1998. This paper analyzes the attacks to the leak and presents a new security method which detects the comparability among those authentication random vectors. The method can distinguish effectively almost all the attacks to protect KI.
