Explanation
RADIUS uses a pre-configured shared secret between the RADIUS client and server to authenticate the parties and protect communications.
Common mistakes.
- B. Kerberos relies on symmetric key cryptography and tickets issued by a trusted Key Distribution Center (KDC), not on a simple pre-shared secret between communicating endpoints.
- C. PKI relies on asymmetric cryptography using public and private key pairs and digital certificates issued by a Certificate Authority, not shared secrets.
- D. LDAP is a directory access protocol used to query and modify directory services and does not inherently rely on shared secrets to protect its communications.
