• A 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. The protocol was named after the character Kerberos (or Cerberus) from Greek mythology. Its designers aimed Kerberos primarily at a client–server model for which it provides mutual authentication—both the user and the server verify each other’s identity. Kerberos protocol messages are protected against eavesdropping and replay attacks. ← Wikipedia ↑ web.mit.edu/kerberos
