摘要：With the development of network technology and the extensive use of e-commerce, the traditional e-commerce processes and its supported technology were faced with challenges. Traditional information retrieval systems have several shortcomings in common, such as delaying in information updating, costing additional host and network resources, and so on. The promise of mobile agent technology is becoming highly attractive. We approach to apply the mobile multi-agent technology to information retrieval in order to build a brand-new system. Although the mobile agent technology advantages information retrieval systems and features such as reducing network load, without continuous network connections and easy to support services, it also brings several new negative problems. The most serious one is the security problem because of agent's mobility and initiative. In this paper, we firstly analyze the drawbacks of current information retrieval systems, and then describe how to employ the mobile multiagent technology to the information retrieval system to improve its performance. What we discuss mainly in this paper is the security problems of the information retrieval system based on mobile agent (IRSMA). We analyze threats to the security of the new system, study out the security policies, and at last establish a robust and secure architecture name MASA (Mobile Agent Security Architecture), which can effectively protect our system, and also adapt to other network application based on mobile agent because of its generality. For implementing the data safe transmission in Internet, a safe transmission mechanism which base on RSA and DES algorithm is put forward.
