Securing Mobile Agent and Reducing Overhead Using Dummy and Monitoring Mobile Agents

A mobile agent is a composition of computer software and data which is able to migrate (move) from one computer to another autonomously and continue its execution on the destination computer. The host computer offers the runtime environment for the mobile agents. Mobile agent technology offers several advantages over conventional client-server computing paradigm: reduced network traffic, efficient resource access, dynamic system adaptation, and support for mobile users. Platforms executing mobile agent can be malicious and try to discover the agent intention, to read data transported by agent or modify the agent data, code or state. One obvious security issue is the protection of hosts against possible attacks from suspicious nodes. The cases where the security of data or reliability of agent became must, we need some method to insure the things discussed above. For increasing the security of original mobile agent, we use dummy agent and monitoring agent which increases the overhead. To reduce the overhead, we reduce the size of data of dummy agent.
