Research On Security Model For Mobile Agent-Based E-Commerce Environment

The emergence of mobile agent technology is arousing revolution on the field of e-commerce and makes the smart e-commerce as the future direction of e-commerce models. However, the advantages of the mobile agent have two sides. It not only injects new vitality into e-commerce, but also brought a new non-traditional security issues which have become obstacles the further development of intelligent e-commerce. Therefore, we must solve the problem of mobile agent security. Specifically, the migration security is one of the difficulties of current research.In allusion to the security issues of the migration process and the shortage of the existing security policies, a security move model with fault tolerance and time limited based on PKI is proposed.The security move model called SecRoute uses a strong authentication system and a trusted platform. It uses the migration confirmed algorithm that is similar to the several handshakes during the migration between the two hosts to ensure the accuracy and security of migration. Meanwhile, during the execution of mobile agent migration, it uses time limited algorithm for detecting the attacks of malicious hosts. In the event of failure, it uses fault tolerance mechanism to restore the fault. The security move model effectively improves security and robustness.This paper realizes the SecRoute algorithm by using Java language and makes simulation experiments on IBM Aglets platform.the results of experiments prove SecRoute validity and feasibility. Compare with other algorithms, the SecRoute has more advantages in security. It has a good performance in identification, fault detection and fault recovery.Finally, the SecRoute algorithm is successfully used into the e-commerce system based on mobile agent. In the environment of the e-commerce system based on mobile agent, the results of a series of experiments prove that the algorithm is effective and feasibility in practical applications environment.
