An Adaptive Kerberos Authentication Protocol With Digital Envelop Technique

Document Type : Original Article

Abstract

The Kerberos Authentication Protocol, developed at MIT, has been widely
adopted by other organizations to identify clients for network services across an insecure
network to protect the privacy and integrity of communications with those services. While
Version 5 has been invented (specified in RFC1510) to overcome Version 4 environmental
shortcomings and technical deficiencies, it has still some issues to be managed. One of the
basic initials of the Kerberos protocol in the inter-realm environment is the process of
sharing keys among realms to guarantee interoperability between them. This paper
provides a proposal for simplifying this process and allowing shared inter-realm keys
through the employment of the digital envelop technique.
