Question 1 of 40Assessment

Why is it important for an Initialization Vector (IV) to be non-repeating (a nonce) when used with algorithms like AES-GCM?

B. A repeating IV will cause the encryption hardware to enter an infinite processing loop.

C. The Certificate Authority will revoke any certificate that uses the same IV twice.
