Practice question 388 of 440 · easy

During Diffie-Hellman key agreement, which information is exchanged to derive the secret?

Choose the single best answer.

  1. A.The entire private key database copied to the other peer.
  2. B.Public DH values; each peer keeps its private value and derives the secret locally.
  3. C.The completed shared secret sent in clear text.
  4. D.Every user password from the LAN.
Show the answer and explanation

✓ Correct answer

  • Public DH values; each peer keeps its private value and derives the secret locally.

DH exchanges public values and derives the shared secret using private values that remain local. Sending the completed secret or private keys would defeat the key-agreement design. LAN user passwords are not the DH exchange.
