Research Of Embedded Mobile Agent System Security Mechanism

With the constant development of the network technology, embedded devices will be integrated into Internet. Currently, the embedded devices using a wireless connection way has disadvantages such as low bandwidth, instability and so forth.Therefore, It can't meet the needs of a large amount of information exchange and share in the information-based society.The advantages of mobile agent technology determines that it can be integrated embedded equipment into Internet better. So the embedded mobile agent emerged.The precondition of using mobile agent technology in embedded equipment is to have an embedded mobile agent platform. However, there is not yet a mature platform can be used for embedded mobile agent directly. Hence, we adopted μAglet which developed by our own laboratory as the experimental platform. It chooses μCLinux with migrated KVM as software platform, and reconstructs IBM's Aglet system to complete the whole system.Security of mobile agent has become the bottleneck that restricts mobile agent technology to achieve universal application. Security of mobile agent transimission, security of mobile agent platform and security of mobile agent is three problem of security of mobile agnet. Openning of network and migration of mobile agent make the mobile agent system security more complicated than other systems. Furthermore, because of limit of embedded device and the disadvantage of wireless network, the security of wireless network is more serious than the mobile agent. Embedded mobile agent application security problem likes a wall which was erected in front of us. This issue tries to make a solution of embedded mobile agent application security.This paper introduces the concepts and the feature of mobile agent. And then we make a detailed analysis of the security problems and the existing solutions faced by mobile agents. The paper also introduces the embedded mobile agent platform μAglet developed in the laboratory. There is the detailed description and analysis of security strategy of mobile agent application in embedded equipment. Finally, the strategy was applied to a practical project.
