Generate Sub-Agent Mechanism to protect mobile agent privacy

In recent years, the mobile agent system has taken a wide area of researchers´ attention. They conducted intensive researches in the security areas to reach an ideal mobile agent model. The security area still needs more efforts to protect the mobile agent system. The protection of the mobile agent is one of these issues. this paper a new mechanism called Generated Sub-Agent Mechanism (GSAM) to protect mobile agent against malicious Hosts has been proposed. The main idea behind GSAM is to generate a sub-mobile agent from the mobile agent in case the mobile agent will visit an untrusted host. The sub-mobile agent visits the untrusted host instead of the mobile agent. After the sub-mobile agent completes its work, it returns to the original mobile agent location and the mobile agent continues its journey. By this way, the untrusted host could not reach the content of the mobile agent. It couldn´t attack the mobile agent behavior. The paper describes all GSMA components. GSMA cost analysis has been done. The analysis result mentions that the increasing of the untrusted host number reduces the time cost and GSMA has not.
