Protection of Mobile agents is one of the most difficult problems in the area of mobile agents' security. There is not a single, comprehensive solution that provides complete protection of agents against malicious hosts. Existing solutions either only detect or to some extent prevent attacks on agents. With detective mechanisms integrity of an agent's code/state is being checked, but there are no effective solutions for confidentiality of agent's code and baggage. In this paper, we propose a system which provides protection of agent's code against illegal modifications, protection during agents' execution, and also protection of agent's baggage. Design of the system is based on a protective approach, which provides better security compared to traditional detective or preventive methods.
