Answer the following questions about block ciphers modes of operation? [30 pts] A. In CBC mode using Ae, bits 15 & 16 in ciphertext block 17 are corrupted during transmission find the possible corrupted bits and blocks of the plaintext? Be specific (10 pts] B. In 16-bit CFB mode (ie the plaintext chunks are 16 bits) where the key generation algorithm is AES, bits 15 & 16 in ciphertext block 17 is corrupted during transmission; find the possible corrupted bits and blocks of the plaintext? Be specific ( 10 pts] C. In 8-bit OFB mode (ie the plaintext chunks are 8 bits) where the key generation algorithm is DES, bits 15 & 16 in ciphertext block 17 is corrupted during transmission; find the possible corrupted bits and blocks of the plaintext? Be specific [ 10 pts) 04- RSA: Assume tha Alice's public key = A. If Alice wants to encrypt the plaintext P= 100 and sends it to Bob, what is the corresponding ciphertext C? (10 pts) B. Assume you are an attacker and intercepted the ciphertext C= 2 sent from Bob to Alice what is the corresponding plaintext in this case? (20 pts)<.e>
