Web3. The Vernam cipher The Vernam Cipher consumes one bit of stored privacy for every bit encrypted and sent over the public channel. It works with the very simple equation, c = m k Take the message bit and exclusive or it with the secret bit, and send the result. The decryption equation is, c k = (m k) k = m (k k) = m 0 = m: Theorem 3.1. Web1 The Fiestel Structure The main weakness of the Vernam and OTP ciphers is transmission of ciphertext bit by bit.
