Question

A ____ is a key-dependent, one-way hash function that allows only specific recipients(symmetric key holders) to access the message digest.a. signature
b. fingerprintc. MAC
d. digest

Answer 1

Answer: (C) MAC

Explanation:

MAC is stand for the message authentication code and it is one of the key dependent hash function. Message authentication provide the data integrity and also the origin of data authentication.

• It basically allow the specific recipients known as the holder of the symmetric key.
• The message authentication code uses the CBC (Cipher block chaining) mode for constructing the MAC algorithm and it also uses the block cipher for the conjunction by using the CBC operations.    

On the other hand, all the options are incorrect as they are not the key dependent hash function.

Therefore, Option (C) is correct.
