Abstract: In the dynamic network security system based on mobile agents, agent migration and fault-tolerance management is a critical issue. However, the issue has always been neglected in early similar works. Aiming at such problem, this paper makes research about it. First, the one-hop migration strategy of agents is presented based on ant algorithms. A novel agent fault-tolerance migration mechanism realised by integrity verification is presented. Then a Combined Agent Migration and Fault-Tolerance Strategy (CAMFS) is presented according to the agent characteristics in a dynamic network security system. Lastly, the advantages of CAMFS are discussed in comparison with other similar works.

Keywords: dynamic network security; mobile agents; agent migration; agent fault tolerance; fault tolerance management; fault tolerant agents; agent-based systems; ant based systems; any colony systems.
