Question: (b) Alice has a message to send and she breaks it into 10 blocks (M1, ..., M10) and encrypts them using AES in CFB mode

(b) Alice has a message to send and she breaks it

(b) Alice has a message to send and she breaks it into 10 blocks (M1, ..., M10) and encrypts them using AES in CFB mode and sends Bob C1,...,C10. Suppose during transmission of ciphertext, there are two bit errors in the transmission of C2 and Bob knows that. Explain which Mi's will Bob correctly decrypt? and which ones are systematically wrong? Briefly explain. (c) We saw that the encryption in CFB mode is sequential. Can the decryption be parallelized? briefly explain
