Hello
I has to look his up - Answer D
Wikipedia states:
In cryptography
, a *stream cipher* is a symmetric key
cipher
where plaintext digits are combined with apseudorandom
cipher digit stream (keystream
). In a stream cipher each plaintext
digit
is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream. An alternative name is a *state cipher*, as the encryption of each digit is dependent on the current state. In practice, a digit is typically a bit
and the combining operation an exclusive-or
(xor).
