Modified authentication protocol and evaluation tool: Kerberos and BAN logic

Abstract

In today’s world the computer network communication increases the efficiency most of the organizations. Hence threats have been increased due to these online transactions/communications. These threats necessitate the researchers to improve the existing security protocols and /or develop the new ones. Authentication Protocols are one of the same which can provide the authentication, confidentiality & integrity. For checking the authenticity of messages exchange process in authentication protocols BAN logic is used. The Kerberos encrypt the information for authentications. Many organizations use it and it has five versions and versions 4 and 5 are latest. In one of over previous paper we have generalized the ticket exchange process of version 5. In this paper to make it more authenticated some modifications are proposed to both BAN and Kerberos and we defined them as R-Kerberos & R-BAN. To achieve this, we have added participant’s physical address (MAC Address) as it is unique to every network adapter and can be used as our secret key.
