5, Which description about the AES cipher isNOTcorrect?(5 points)
A. The block size of DES is 64 bits.
B. The DES cipher is based on the Feistel Cipher Structure.
C. When the plaintext is encrypted using DES twice (Double DES) with two different keys, the key search space increases from 256to 2112.
D. Triple DES is more secure compared with original DES.
Hint: The key space consists of all possible keys.
