A mobile agent security management

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 manager), 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.
