APUC: A Novel Authentication Protocol for Ubiquitous Computing Environment

In ubiquitous computing environments users expect to access resources and services anytime and anywhere, leading to serious security risks. The concept of user authentication to a domain is not possible. A novel authentication protocol for ubiquitous computing has been proposed to assure user authentication. Furthermore, as the essential property of ubiquitous computing, unobtrusiveness has also been achieved. We creatively implement hybrid asymmetric-key /symmetric-key algorithm to make the protocol more security as well as suffice severe resource constraints.
