Location-Based Kerberos Authentication Protocol

Online communication offers organizations greater efficiency. However, online processes increase the threat level during message transfer. This necessitates researchers to develop and improve security protocols in order to enhance the security of communication lines. Despite the evaluation and acceptance of many authentication protocols, online communications remain insecure, we propose to add the user's physical location as a new authentication factor into Kerberos protocol and call it N-Kerberos protocol, and we validate the new form of Kerberos (N-Kerberos).
