1 Trust in Mobile Agent Systems

The protection of mobile agent systems continues to be an active area of research that will enable future applications to utilize this paradigm of computing. Agent systems and mobile applications must balance security requirements with available security mechanisms in order to meet application level security goals. We pose models for viewing security in application contexts that aid the mobile agent system design process. Our models relate security attributes for principals in mobile architecture to support reasoning about applicable security requirements, trust expression among principals, and mechanisms for protection.
