Abstract

In the present paper, a new protocol for authentication and key distribution is proposed. The new protocol has the aim to achieve a comparable performance with the Kerberos protocol and overcome its drawbacks. For authentication of the exchanged messages during authentication and key distribution, the new protocol uses the Message Authentication Codes (MAC) to exchange the Diffie-Hellman components. On the other hand, the new protocol uses nonces to ensure the freshness of the exchanged messages. Subsequently, there is no need for clock synchronization which will simplify the system requirements. The new protocol is analyzed using queuing model, the performance analysis of the new protocol shows that the new protocol has a comparable performance with the Kerberos protocol for short messages and outperforms it for large messages.

Keywords

Advance Encryption Standard Security Manager Short Message Message Authentication Code Clock Synchronization 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
