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: 4An Architecture for Verification of Access Control Policies With Multi Agent System Ontologies(Institute of Electrical and Electronics Engineers Inc., 2009) Tekbacak, Fatih; Tuğlular, Tuğkan; Dikenelli, OğuzMulti-agent systems (MAS) which communicate with intra-domain and inter-domain agent platforms have access control requirements. Instead of a central mechanism, a fine-graned access control mechanism could have been applied to MAS platforms. This paper emphasizes MAS-based domain and security ontologies with XACML-based access control approach for MAS platforms. The domain dependent behaviour and access control parameters in agent ontologies could be combined within a common XACML policy document that is used through different MAS applications. Agent-based access control requirements and common XACML policy documents should be consistent to enforce policies for MAS. To obtain this condition, the translation of organizational policies and platform based policies have to be considered in detail and the verified policy features have to be enforced in MAS to provide access for resources.
