The study for protecting mobile agents based on time checking technology

As a new distributed computing technology, mobile agent shows its wide prospect of application. But Some security problems are still exist in the widespread deployment of mobile agents´ application. Since the mobile agent is completely exposed to remote host and easily be isolated and attacked by the malicious hosts, the protection of mobile agent on remote agent platform matters much. Obfuscation Policy is used by the mobile agents´ producers to enforce the level of security of agents. Some behavioral transformations are made to the agent before sending it to remote platform in order to hide the real code. This paper presents a protection scheme of mobile agent in Internet application, which combining data obfuscation and time checking technology together to verify the security of target node. Method of how to obtain related data in time checking is given also. The protection scheme is tested in actual network management environment, which can effectively identify the malicious node.
