Abstract :
In third generation mobile telecommunication systems such as UMTS, one of the important problems for value-added services is to check the recoverability of costs used by a mobile user. We present an efficient public-key protocol for mutual authentication and key exchange designed for value-added services in UMTS. The proposed ticket based authentication and payment protocol provides an efficient way for VASP to check the recoverability of costs without communication with the online TTP. Furthermore, the ticket based protocol can provide anonymous service usage for a mobile user
