A Secure and Fault Tolerant Platform for Mobile Agent Systems

Abstract

Mobile agents offer a new paradigm in the field of distributed computing. Mobile agent is a program which can migrate from one machine to another machine in order to fulfill the client’s needs. Since it moves from machine to machine on the demand of client, there is threat to the data it carries, from the malicious node or hacker who can steal or change the confidential data of the client. In this paper, we have proposed an integrated framework which is fault tolerant as well as secure from such malicious nodes or hackers. We have applied encryption algorithm for data security and fault tolerant mechanism to avoid any kind of fault using clone and check-pointing with location tracking mechanism. We have implemented the proposed approach and evaluated the time taken by the agent on the basis of various parameters with its fault tolerant and security feature.
