Webabout 20 years ago [9]. A common type of stream cipher is the binary additive stream cipher, in which the keystream, the plaintext, and the ciphertext are binary sequences. The keystream is produced by a keystream generator which takes a secret key and an initial value (IV) as a seed and generates a long pseudo-random sequence of 0s and 1s.

WebSuppose that a binary additive stream cipher (such as the one time pad) has been used to encrypt an electronic funds transfer. Assuming that no other cryptographic processing is used, show that an attacker can change the amount of the funds transfer without knowing anything about the key used. WebA MAC is particularly important for binary additive stream ciphers. For this class of ciphers, ipping a bit of the ciphertext will ip the corresponding bit of the plaintext, and only a ect that one bit. This can be used by an attacker to change messages. A MAC will prevent this type of attack.
