A critical promotion factor of e-Commerce is message authentication, the procedure that allows communicating parties to verify received messages as authentic. The client-server system has been traditionally used for authentication service. As distributed computing environment has been complicated more and more, Agent system is developed and used extensively for security service. We have designed and successfully tested an agent model for security service which we have named NMAP(New Message Authentication Protocol) to deal with message authentication in the public key cryptosystem. The NMAP's performance has been shown by various trials of message authentication based on file size and key length. The NMAP's overall performance on the processing speed is shown to be superior to that of client-server system named PGP. This suggested system will provide an active e-Commerce and non-interactive authentication service.
