Implementing Cisco Network Security (IINS, legacy) — Question 102

Which components does HMAC use to determine the authenticity and integrity of a message?

Answer options

• A. The password
• B. The hash
• C. The key

Correct answer:

Explanation

HMAC relies on both the key and the hash function to ensure message integrity and authenticity. The password is not a component of HMAC; rather, it uses a secret key combined with the message to produce a hash. Therefore, the correct answer is C, as the key is essential for HMAC operations.
