Location-aware access control for pervasive computing environments

Abstract

In pervasive computing environments certain applications are interested in a user's location in order to provide a service. Such applications would benefit from an architecture that enables users to prove their location prior to requesting a service. We present PA C, an architecture for location-aware access control in pervasive computing environments, where users authenticate their location in order to gain access to resources. PAC preserves user anonymity and uses lightweight security. We evaluate our architecture with respect to its security and its scalability as the number of resources and users increase.
