Kerberos is a protocol for the secure authentication of principals ( users/systems/applications ) which operates over a network medium which may not be secure. It uses encryption to provide confidentiality and integrity of authentication functions. It also provides Single Sign-on features and encryption of application data streams which traverse a network. My Kerberos page has some resources and information related to the work I've been doing with Kerberos.
