The mobile agent security against malicious hosts is one of the most important subjects in mobile agent technology. An extended requirement for an agent security in different applications is to provide it with anonymity property in such a way that the agent can travel in the network without exposing its owner identity and its itinerary. For this purpose, an agent anonymity protocol is proposed to maintain the anonymity of the agent owner and the agent itinerary. The introduced anonymous agent is also applied to disarm the host against the agent instead of using an armed agent, that is, an agent equipped with protection mechanisms. The analytical discussion demonstrated that this protocol preserves the autonomy of the agent in choosing the migration path and is also resistant against known traffic analysis attacks in mobile agent systems with plausible assumption. Moreover, it is feasible and adjustable regarding the required level of anonymity.
