Abstract
Abstract:
Kerberos is a widely used authentication scheme based on symmetric key cryptography,
although Kerberos is a part of MIT’s Project Athena it has been adopted by many other
organizations for their own purposes. And is being discussed as a possible standard.
Despite Kerberos’s many strengths, a number of limitations and some weaknesses have
appeared due to MIT’s environment that needs only user-to-server authentication and
others due to deficiencies in the protocol design. In this paper an improved scheme
using the Public Key cryptography will be proposed to enhance its security strength to
overcome these limitations and weaknesses.
