Ubiquitous access and pervasive computing enable i nnovative services and provide the service access in every situation. People currently rely on numerous fo rms of identities to access remote or proximity services. The inconvenience of possessing and using these identitie s creates significant security vulnerability. This paper proposes an architecture that integrates the identities required to access various remote and proximity services. In the mechanism, identities are distributed into the user’s personal device and a secure network space. Third party identity providers along with the mobile network provide the underlying secure infrastructure for identity info rmation exchange. In this regard, the use of multi- factor authentication contexts meets different levels of service access security requirements. At the end, a prototypical implementation demonstrates a service access scenario based on the proposed mechanism.
