A Trust-based Dynamic Secure Service Discovery Model for Pervasive Computing

To scope with the challenges posed by pervasive computing, a service discovery model is needed that can resolve security and effectively issues for pervasive computing. In the paper we present a trust-based dynamic secure service discovery model, and we use SAO architecture in our scheme. We classify the services that can be provided by devices in pervasive environment into three levels, different level of services being discovered in different manners. In this paper we also incorporate a trust manage model to calculate the trust value of a service requestor.
