An inter-domain authentication scheme for pervasive computing environment

In a pervasive computing environment, mobile users often roam into foreign domains. Consequently, mutual authentication between the user and the service provider in different domains becomes a critical issue. In this paper, a fast and secure inter-domain authentication and key establishment scheme, namely IDAS, is proposed. IDAS adopts Biometrics to guarantee the uniqueness and privacy of users and adopts signcryption to generate a secure session key. IDAS can not only reduce the burden of certificates management, but also protect the users and authentication servers against fraud. Compared with some other authentication methods, our approach is superior with faster key exchange and authentication, as well as more privacy. The correctness is verified with the Syverson and Van Oorschot (SVO) logic.
