- What are the potential limitations of Electronic Code Book (ECB)? If one ciphertext block is corrupted during the transmission, all subsequent ciphertext blocks cannot be decrypted unless until corrupted block is successfully retransmitted. Repetitive information contained in the plaintext may show in the ciphertext, if aligned with blocks. If the same message (e.g., an SSN) is encrypted (with the same key) and sent twice, their ciphertexts are the same. It needs an initialization vector to operate.Permutation ciphers hide the message contents by rearranging the order of the letters. choose one: true falseWhich parameters and design choices determine the actual algorithm of a Feistel cipher?
