The Mobile Agent Security Enhanced by Trusted Computing Technology
The mobile agent (MA) technology has been widely used to archive plenty of applications in distributed systems. The mobile agents are completely exposed in different hosts and easy to be attacked by different adversaries. In this paper, the requirements for security of MA are analyzed. Considering the security and safety problems both in software and hardware, we construct a way to build a trusted computing environment for MA by using the trusted computing technology. The trusted platform module (TPM) is integrated into the mobile agent platform. In the TPM enabled schemes for MA, some innovations, such as authentication, MA software integrity, secure group communication and secure storage, are provided to improve the security of MA
