IMPROVED 3GPP-AKA METHOD FOR AN EFFICIENT MANAGEMENT OF AN AUTHENTICATION PROCEDURE IN A 3G NETWORK, CAPABLE OF SOLVING AN ASYNCHRONOUS PROBLEM OF A CERTIFICATION VECTOR

摘要

PURPOSE: An improved 3GPP-AKA method for an efficient management of an authentication procedure in a 3G network are provided to solve the asynchronous problem of the authentication vector by using a time stamp shared by an USIM(Universal Subscriber Identity Module) terminal and a service network. CONSTITUTION: In an improved 3GPP-aka method for an efficient management of an authentication procedure in a 3G network, a user registration and authentication vector distribution are performed in AKA(Authentication & Key Agreement) process(S110,S111,S112). A mutual certification between MS and SN and an encrypting key exchange are operated in the AKA process(S113,S114).
