Mobile agents are believed to be playing an important role in future e-commerce systems, offering great flexibility and improved performance. Mobile agents are processes which can autonomously migrate from host to host. The migration path followed by an agent can be abstracted for programming convenience into an itinerary. A flexible structure of itinerary is used in Concordia or Ajanta Agent Systems, using sequence, alternative, and set entries.

Mobile agents are processes which can autonomously migrate from host to host. The migration path followed by an agent can be abstracted for programming convenience into an itinerary. This is composed of tuples of the form (server name, method specification). A flexible structure of itinerary is specified in [24] using sequence, alternative and set entries.Despite its many practical benefits, mobile agent technology creates significant new security threats from malicious agents and hosts. In order to protect mobile agents, several itinerary protection protocols have been presented. However, they can only be applied to sequence entries.In this paper, we introduce a protocol for each kind of entry in order to protect general flexible itineraries established in free-roaming mobile agents. Our proposal uses ElGamal cryptosystem and a public-key infrastructure. Nevertheless, any public cryptosystem may be used.

This paper introduces MARISM-A, an Architecture for Mobile Agents with Recursive Itinerary and Secure Migration. MARISM-A is a secure mobile agent platform providing complex security mechanisms to protect migration, confidentiality and integrity of agents. This is indeed one of the more novel features of this platform: itinerary, data and code of the agent are protected through a new model of mobile agents. Moreover, MARISM-A is extendable with user defined agent architectures. Mobile and nomadic computing can be implemented with MARISM-A, even though it has been specially designed to develop sea-of-data applications.
