Kerberos is one of the solutions for network security problems since it provides strong secret key cryptography over the insecure networks. Through the Kerberos authentication protocol, a client can prove its identity to a server (and vice versa) across an insecure network connection such as on Internet. In this comparative research paper, the Kerberos authentication protocol is extended and strengthened using x.509 with the integration of newer authentication system which is compared with previous authentication systems. In addition to this, RSA encryption mechanism used to provide authentication and security for the most communication systems replaced with Elliptic Curve Cryptography (ECC) encryption in Kerberos during authentication progress through simulation to expose possible efficient alternatives for key generation and to enhance security.
