A Secure Mobile Agent System against Tailgating Attacks

Abstract

Problem statement: A lot of real time applications have extended their hands towards Mobile Agents to accomplish various tasks, due to its flexibility in its functionalities. Since Mobile Agent Systems are used in a distributed environment, it is obvious that they may be vulnerable to various security threats. Most of the security threats faced by the mobile agent systems are overcome by existing security algorithms and architectures. One of the major threats which are not of much focus in a mobile agent system is the Tailgating attack. Approach: In this study, mobile agent system architecture has been proposed to overcome Tailgating. The proposed architecture uses the mechanism of Dual Check-point to preclude Tailgating attacks. Also, to support the mechanism, we use fragmentation and defragmentation techniques. This assures a free flow of data within the system. Results: The results obtained prove that the system is much efficient in its operations as well is immune to Tailgating attacks. Conclusion: The security of the system is improved with the implementation of the Dual Check-point method.
