英文摘要 | In the third generation mobile telecommunication systems such as UMTS, one of the important problems for value-added services is to verify the recoverability of costs used by a mobile user. Previous authentication and payment protocol for value-added services by a mobile user across multiple service domains, rely on the concept of the on-line TTP, which serves as the user’s certification authority. In the third generation systems with many service providers, a wide range of services, and a diverse user population, authentication mechanisms with the on-line TTP provide a far from ideal solution. In this paper we propose a service access scheme based on the notion of the ticket for value-added services in UMTS. Proposed ticket based authentication and payment scheme provides an efficient way for VASP to check the recoverability of costs without communication with the on-line TTP. Furthermore, proposed ticker-based protocol can provide anonymous service usage for a mobile user. |
