Mobile Agent System-based Security Technology

This paper mainly disserates security problems in Mobile Agent-based Systems. After discussing the history, the current situation and the trend of the distributed computation model, the article describes the Mobile Agent technique in-depth. Then, the paper analyzes the security problems in Mobile Agent Systems and their countermeasures in existence detailedly, and summarizes the security solutions of the present Mobile Agent Systems. In the following part, Combined with the security problems in LKMIS, this article brings forward a security framework to strenthen the security of Mobile Agent-based System. At last, with the framework's implemention in LKMIS, the paper gives the evaluation of the Security Framework's performance, and makes some ameliorative suggestion.
