Kerberos is a network authentication protocol & is designed to provide strong authentication for client/server applications by using secret-key cryptography. Our research was aimed at enhancing the security of transactions over a network. In this study, we used Kerberos Encryption Technique for authentication and transaction security in the network. Further, we created an Authentication Server that used to derive a 64 bit key from user's password. This password was of arbitrary length. The generated key then was used by authentication server, to encrypt ticket granting ticket + session key....
