Abstract—Mobile agent technology quickly emerged in the field of distributed computing. Its use offers several advantages compared to the classic Client / Server model such as reducing network traffic, using disconnected computing, and offering more flexibility in application development, etc. Although mobile agent technology is considered as a powerful tool, it has some security problems that need to be overcome. Mobile agents, due to their mobility are vulnerable to attacks in a hostile environment. For this reason, it is necessary to put effective security techniques to protect them when they move from their home host to a new one. In this paper, we propose two security mechanisms to enhance mobile agent security. On one hand, we use a cryptographic trace to ensure mobile agent integrity and origin authentication, and on the other hand an SOS agent monitor’s model is proposed to protect the mobile agent system against malicious hosts and DOS attacks. An implementation of the SOS agent approach will be presented.
