Conference Object Citation - Scopus: 1A Semantic Based Certification and Access Control Approach Using Security Patterns on Seagent(Knowledge Systems Institute, 2008) Tekbacak, Fatih; Tuğlular, Tuğkan; Dikenelli, OğuzIn this paper, we propose a security infrastructure for communication between agents adaptable to FIPA security specifications by employing security patterns and semantic based policy descriptions. Security patterns are used as a generalized approach for generating security based services. This paper analyzes the authentication and semantic based access control among agents by using the security patterns.Conference Object Citation - Scopus: 1Policies for Role Based Agents in Environments With Changing Ontologies(International Foundation for Autonomous Agents and Multiagent Systems, 2011) Tekbacak, Fatih; Tuğlular, Tuğkan; Dikenelli, OğuzSoftware agents try to achieve the goals of roles that they have in an environment. It is supposed that the dynamic structure of role based agents can be connected with updatable domain ontologies of the environment. Ontology evolution can cause the update of agent behaviors or access restrictions to ontological elements. So regulation for the agent behaviors may be needed. Our motivation is to create a suitable policy model for agents, environments and organizations when ontologies in the environment can change.
