Abstract
En 中文
Mobile agent technology is an emerging paradigm in distributed computing environment and it holds a potential status in the relevant research field due to its unique capabilities like flexibility, dynamic customization and robust interaction in unreliable networks. But the limited security perspectives and shortfalls of the mobile agent environments degrade its usage in a variety of application domains. Even though some of the protection models are available for protecting the environments, they are not efficient in handling the security issues. To make the mobile agent environment secure, this paper proposed advanced models to improve the efficiency of the existing Malicious Identification Police model for scanning the incoming agent to detect the malicious activities and to overcome the availability of vulnerabilities in the existing Root Canal algorithm for code integrity checks. The MIP model is extended with the policy to differentiate the agent owners in the distributed environment and the Root Canal algorithm is improved as eXtended Root Canal algorithm. The experimental results of the advanced models show that though these mechanisms take more time complexity than the existing malicious identification police model and Root Canal model, these models are efficient in protecting the agent code integrity and scanning the agent for malicious activities. Also the new models possess less time complexity compared to the other related existing models in the secure mobile agent environment. (C) 2010 Elsevier Ltd. All rights reserved.
