Answer: D. Kerberos

Explanation:

Kerberos is an authentication mechanism whereby both the client and the server provide authentication using a secret key cryptography.

Kerberos works on the key distribution center(KDC) because each time a client is sending authentication it needs to be verified for the clints name and password from the KDC database before it is granted to receive reply from the server.

However using Kerberos it ensures that the password are encrypted using secret key cryptography so that it could not be read by others on the network. The encrpyted password is send to the clients when it first request for ticket to the KDC.
