Abstract

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.

Key words： COMP128;strongKI;comparability
