【Abstract】 As a new distributed computing technology, mobile agent has a wide application prospect. But the protection of mobile agent in remote agent platform is an awkward problem because agent is completely exposed in remote host and it is easy to be isolated and attacked by the malicious host. This paper puts forward a solution based on JavaCard and it uses JavaCard to supply a secure execution environment for agent. First, attack of agent and current research status are analyzed, and then the detailed solution based on JavaCard is given. After that the partition method and distribution algorithm are discussed, and finally the experiment system model is analysed and testified.更多还原
