TRUST BASED ACCESS AND DELEGATION CONTROL IN PERVASIVE COMPUTING

Abstract

With the increasing amount of the handheld devices and respective pervasive services, the issues of security have alarmingly risen. One can wonder about the pervasive services to be free of every security flaw. The paper suggests a mechanism for a trust based ad‐hoc authentication with a distributed mechanism and authorization to pervasive services. The openness of a truly pervasive environment has been encountered with its interaction history and recommendation from trustworthy sources. Proposed distributed security architecture is realized with a web based framework managing the user registration of the university at a novel level. The architecture is designed to provide secure autonomous services for an assumed pervasive based scenario. The nature of pervasiveness is fulfilled by allowing the novel user to proceed in the system but with the minimum trust initially which changes with the passage of time, dynamically depending on the actions which the user performs. Certain actions on the specified services are granted to the user on the basis of trust level and user category. Delegation access control module exists with respect to the time period.
