  • Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography.
  • It is a computer network authentication protocol that works on the basis of ‘tickets’ to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner.
  • It uses strong cryptography so that a client can prove its identity to a server (and vice versa) across an insecure network connection.
  • The messages are protected against eavesdropping and replay attacks.
