A Scheme for Protecting Mobile Agents Based on Combining Obfuscated Data and Time Checking Technology

Mobile agents are programs that travel autonomously through a computer network in order to perform some computation or gather information on behalf of a human user or an application. In most applications, the security of mobile agents is of the utmost importance. Obfuscation is a technique in which the mobile code producer enforces the security policy by applying a behavior transformation to the code before sending it to run on different platforms. This paper presents a protection scheme of mobile agent in network application, which combining obfuscated data and time checking technology to verify the security of node. How to obtain important data in time checking is given also. The protection scheme is tested in actual network management environment, which can effectively identify the malicious node.
