Design, Implementation, and Experimentation on Mobile Agent Security for Electronic Commerce Applications

In this paper, a Shopping Information Agent System (SIAS) is built based on mobile agent technology. It sends out agents to di erent hosts in an electronic marketplace. The agents collect and report information such as prices and availabilities about products speci ed by users. Snapshots of the system in use are shown. Security is a major problem of mobile agent systems, especially when money transactions are concerned. Possible security attacks by malicious hosts to agents in SIAS are discussed, and a solution to prevent these attacks is presented. Finally, security of the solution is analyzed, and the performance overhead introduced is
