The user, Alice, who wishes to communicate with another user, Bob, authenticates to the KDC and is furnished a (ticket) by the KDC to use to authenticate with Bob. When Kerberos authentication is based on passwords, the protocol is known to be vulnerable to off-line dictionary attacks by eavesdroppers who capture the initial user-to-KDC exchange.

Nonce: A value used in security protocols that is never repeated with the same key. For example, challenges used in challenge-response authentication protocols generally must not be repeated until authentication keys are changed, or there is a possibility of a replay attack. Using a nonce as a challenge is a different requirement than a random challenge, because a nonce is not necessarily unpredictable.

For example, the TLS protocol is often used with a Verifier's public key certificate to (1) authenticate the Verifier to the Claimant, (2) establish an encrypted session between the Verifier and Claimant, and (3) transmit the Claimant's password to the Verifier. The encrypted TLS session protects the Claimant's password from eavesdroppers.
