The Mobile Agent Security Research Based On JAVA CARD

Recently , with the pervasive application of Internet and on the advent of mobile computing, researches on mobile agent are very hot in both academic and industrial world. Many corporations, universities and research institutions have developed their own mobile agent systems. But there will be a long time before we can apply this new technology successfully because of its security problem.In this paper, we put forward our own improved protection programmers on the basis of with reference to the existing mobile agent protection programmers. Through comparative analysis, the improved protection programme can partly solve the security problems of Mobile Agents.The main work are as follows in the article:In order to resolve the problem that Mobile agent may be attacked by hackers while roaming in the network, we put forward our own improved protection programmers by Encryption technology and SSL(Secure Sockets Layer ) Communication Protocol. Thus, Ensure the security of mobile agent in the transfer.We put forward our own improved protection programmers to the problem that host or agent execution environment may be attacked by malicious agent through combining digital signature technology and developing security strategy. The improved programmer ensure the normal operation and communication of the equipment and agents, after the host is protected in the language level and application-level.The problem is the focus of this paper that Mobile agent may be attacked by malicious host or agent execution environment. Our research emphasizes on whether the Java Card can be used to protect mobile agent, and we give our own improved scheme. The use of the hardware that it is reliable and can withstand attack put forward a more general approach for the settlement of the issue presents.Finally, we give one security model based on MASS and Java Card for the existing problems of Java Card hardware resources are very limited.
