What is the use of Kerberos protocol? Kerberos is an authentication protocol in a compute network that makes the nodes communicates over a non-secure network for providing their identification to one another in most secure manner. The protocol design is aimed at a client-server model, which provides the mutual authentication – the identification of both users and the client verifies each other’s identity. The messages that are handled by Kerberos protocol are protected against ‘eavesdropping’ and ‘replay attacks’. Kerberos was built on symmetric key cryptography and it needs a trusted third party.
