Further Improvements to the Kerberos Timed Authentication Protocol

Authentication mechanisms coupled with strong encryption techniques are used for security purposes; however, at times, well-equipped intruders succeed in breaking encryption and compromising data integrity, confidentiality and trust. Kerberos is a widely used computer network authentication protocol which allows individuals communicating over an insecure network to prove their identity to one another in a secure manner. This paper presents an approach that involves temporary interruption to link/server access with a new authentication protocol that delays the decryption with timed authentication. The analysis and verification of authentication properties and results of the designed protocol arc presented.
