CompTIA Security+ (SY0-501) — Question 268

Which of the following is an asymmetric function that generates a new and separate key every time it runs?

Answer options

• A. RSA
• B. DSA
• C. DHE
• D. HMAC
• E. PBKDF2

Correct answer: C

Explanation

DHE (Diffie-Hellman Ephemeral) is designed to generate a new key for each session, making it a perfect fit for the question. RSA and DSA are not designed to generate new keys on each execution, while HMAC and PBKDF2 are not asymmetric functions.
