On the approach of combining trust and security for securing mobile agents: Trust enhanced security

Mobile Agent systems employ a number of security features to address the various threats. Despite the employment of various security features by most systems, there is a lack of security standard that covers all the aspects of their operations. Due to the mobility feature in distributed systems, various security concerns like auditing, secure communication, availability, accountability becomes further complicated and hence prove to abuse and misuse. Examining the above problems and uncertainty in behavior of mobile agents, it is thought to combine security with trust. We refer it to trust enhanced security that combines trust decisions into security decisions-making processes through explicit specification and management of security-related trust relationships. Trust Management entails collecting the information necessary to establish a trust relationship and dynamically monitoring and adjusting the existing trust relationships.
