A Security Technology for Mobile Agent System Improved by Trusted Computing Platform

As a promising distributed computing technology, mobile agent (MA) can be used in many fields. But the security problem of MA is a barrier for application of MA technology. In this paper, we analyzed the security problems of mobile agent system exposed in opening environment and proposed a model system for mobile agent is proposed. In this system, the mobile agent security is enhanced by the trusted computing technology. The mobile agent security supporting environment (MASSE) is designed by using trusted software stack and trusted computing platform. We described the work of TSS core services and the TSS service provider in MASSE. Some MA security services, such as MA authentication, MA credential, MA proxy service, role based access control for MA are introduced in this paper. The working process of MASSE is also described.
