Explanation

Kerberos was developed in the 1980s at MIT as part of Project Athena. It is a network authentication protocol that uses a trusted third party called the Key Distribution Center (KDC) - composed of an Authentication Server (AS) and a Ticket Granting Server (TGS) - to issue time-limited tickets that prove a user's identity without transmitting passwords over the network. SESAME, KryptoKnight, and NetSP are alternative SSO/authentication systems but were not developed under Project Athena.
