碩士 === 國立交通大學 === 資訊工程系 === 88 === Security is considered as an important issue for mobile communication systems. Most of current authentication schemes for mobile systems only have simple security functions, such as subscribers’ authentication and the confidentiality of the communications on radio paths. They usually have some weaknesses, such as the leakage of user identity and the update overhead of temporary identity, and the security requirements of third-generation mobile systems (IMT-2000, UMTS) are not fulfilled. In this thesis, we propose a secure and flexible authentication framework for mobile communications. The new framework provides the flexibility of authentication, which enables service providers to dynamically choose the authentication mechanisms without the cooperation of network operators in visited domains. Based on the new authentication framework, a secure authentication protocols is proposed. The proposed protocol contains the security features required in third-generation mobile systems, such as mutual authentication, user anonymity, and end-to-end security. Not only for the authentication of call setup, our protocol can also be efficiently applied to a variety of mobile services, such as Internet services.
