Recent multi agent systems are characterized by decentralized control, autonomy and local views. The application of multiagent systems on open environment such as internet creates new challenges especially with respect to security issues such as authentication, authorization and privacy. Two very common attacks that faced by multiagent systems are man-in-the-middle attacks and replay attacks. This paper proposes an authentication approach for the solution of these attacks to some security problems in open multi-agent systems using Digital signature. Every agent in the system needs to create a key-pair. The identity of the agent can now be verified by checking whether the agent can correctly decrypt a message encrypted with public key.
