Abstract: Despite its many practical benefits, mobile agent technology results in significant new security threats from both maliciousagents and hosts. This paper investigates the problems and approaches of mobile agents, which shows that bi-directional and layered securitymodel may be a good idea to resolve the security problems in mobile agent systems. Other topics about mobile agent security, such asconstrained execution and virus detection, are also discussed.
