SECURE COMMUNICATION PROTOCOL FOR PROTECTING COMPUTATION RESULT OF FREE ROAMING MOBILE AGENT

Abstract

Mobile agent plays an important role in developing applications of open, distributed and mixed environments, such as the internet. Mobile agent or mobile software agent is piece of software that can operate autonomously to accomplish user assigned task. To explain more, mobile agent is the process which can migrate to hosts autonomously. As an agent travels to do execution in different environment in different host or servers, the agents are in need of protecting themselves and their data from various types of attacks. So providing security to the mobile agent (static code) and its data (dynamic code) is an emerging need in Mobile Agent Technology. The change in Mobile Agent (MA) code can be identified due its static nature where as finding change in mobile agent data is the biggest challenge especially in malicious host’s attacks. This study presents Clone Return Process (CRP) method to protect the data of free roaming mobile agent against colluded truncation attack. By using CRP, malicious host are identified and recovery of mobile agent is easily done. So free roaming mobile agent communicates with other servers and protects its computation results (data) in an efficient way.
