Abstract
As the proliferation of Internet, mobile agent related technologies are examined for possible growth and evaluation. In information retrieval, network and distributed system management, and electronic commerce, a mobile agent is more flexible than the traditional communication paradigm. Despite the performance benefits, a mobile agent is not used widely in the market because it is very vulnerable to a variety of attacks. In many studies related the security vulnerability for a mobile agent, the high security causes the performance to degrade. In this paper, we propose and evaluate an efficient security model for a mobile agent using TDGM(Trusted Domain and Guide Manger), which provides three kinds of services: the trusted domain management, the security service and the travel plan guide. The result of our experiments clearly shows that this model provides high security and mitigates the performance degradation.
