A Correct answer
Explanation

Kerberos uses symmetric encryption (secret key cryptography) to authenticate users and services. It relies on a trusted third-party Key Distribution Center (KDC) that shares secret keys with all parties. Asymmetric encryption uses public-private key pairs, digital signatures provide non-repudiation, and block ciphers are symmetric encryption algorithms but not the specific answer for Kerberos authentication.
