The security of any MAC function based on an embedded hash function depends in some way on the cryptographic strength of the underlying hash function.

Question

Quizplus · Accepted Answer

The security of any message authentication code (MAC) function is directly related to the cryptographic strength of the underlying hash function. If the hash function is weak, then the MAC function will also be weak and vulnerable to attacks such as collision attacks and preimage attacks. Therefore, the statement is true.
