A Network Authentication Protocol Based on Kerberos

It will focus on cryptographic protocols intended to achieve authentication over the networks. It aims to design a user authentication protocol that is not susceptible to password guessing attacks. It presents an authentication protocol based on the widely deployed Kerberos protocol with a little modification in the Kerberos database. The proposed protocol will be independent of the user password. The KDC will generate the realm principle secret key based on a saved profile in its database. The KDC will save a profile for every instance in the realm that it mange. This profile will be hashed and then, the output digest will be encrypted to generate the secret key.
