Abstract

Mobile agent system comes into the spotlight since it contributes largely to mobile computing on distributed network environment. However, this system has a number of significant security problems. In this paper, we analyze security attacks to mobile agent system presented by NIST[3]. In order to protect this system from them, we suggest a security protocol for mobile agent system by employing ID based key distribution and digital multi-signature scheme. To solve these problems described in NIST, securities for mobile agent and agent platform should be accomplished. Comparing with other protocols, our protocol performs both of these securities, while other protocols mentioned only one of them. Proposed protocol satisfies simplicity of key management, providing security service such as confidentiality, integrity, authentication and preventing reputation, liveness guarantee, protection of excution-result data and preventing replay attack. Furthermore, it is designed to detect message modification immediately by verifying each step of agent execution at a corresponding server.
