SECURED TRUST COMMUNICATION IN MULTI-AGENT SYSTEMS?

Nowadays security and privacy issues take a major role in multi-agent system. Mostly multiagent systems are open and dynamic in nature. This nature surely introduces a problem by providing secured communication. Message-Digest5 is presented to some security problems in multi agent systems based on distributed trust and the delegation of permissions and credibility. In particular, an agent will receive requests and assertions from other agents and must decide how to act on the requests and assess the credibility of the assertions, because sometimes malicious agents start to behave in unpredictable way. The multi-agent systems which is becoming critical for sustaining good service quality, is the even distribution of workload among service providing agents. For that a dynamic trust computation model called secured trust is introduced. This reduces to authentication the reliable identification of agents’ true identity. In this project the Multi-Agent System (MAS) concepts is applied to facilitate the authentication and the authorization process in order to work with multi-clients more dynamically and efficiently. The key pair and Certification Authority are deployed to encrypt/decrypt electronic data or transaction, or sign/authenticate the sender and the recipient.
