In this paper, the authors present a new secure authentication system is proposed that significantly reduces the possibility of frauds. This scheme is primarily designed for organizations. It is based on the Kerberos cryptographic framework that has been proven to be secure after being used in real world for decades. The proposed system allows tokens to be exchanged between the server and clients. The token is generated from the client information. A token is cryptographically secure and valid only for the designated client, and therefore it is robust against eavesdropping.
