WebThe third task is for graduate students, and is to compute the CMAC (Cipher-based Message Authentication Code) using AES with 128 bits, of the same input file. This is done using the CMAC class of the Crypto++ library. The CMAC class takes a key as input and computes the CMAC of the input file using the AES algorithm with 128 bits. WebApr 1, 2015 · An AES decryption with the correct key will return the original message, but an AES decryption with an incorrect key will produce garbage data as an output. The AES cipher itself provides no indication that the key was wrong - there's no point during the decryption at which the algorithm says "hey, wait a minute, this doesn't make sense!"
