SYSTEM AND METHOD FOR BUNDLE AUTHENTICATION

摘要

PURPOSE: A bundle authentication system and a method are provided to safely authenticate from a malicious attack of an attacker by utilizing a BAK generated through an cryptology key which generated in an access authentication process. CONSTITUTION: A subscriber terminal(110) calculates a BAK based on an EMSK. The subscriber terminal calculates an Auth value with confirming the subscriber terminal with successfully implementing the access authentication. An integrated authorization server(120) practices the access authentication with the subscriber terminal. The integrated authorization server calculates the BAK based on the EMSK by confirming an IMPI. The integrated authorization server transmits a response message to a S-CSC- FE(130) by calculating the Auth value. The S-CSC-FE transmits the IMPI to the integrated authorization server.
