- In cryptography, a
keystream is a
stream of
random or
pseudorandom characters that are
combined with a
plaintext message to
produce an
encrypted message...
-
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...
- insecure. It is
especially vulnerable when the
beginning of the
output keystream is not discarded, or when
nonrandom or
related keys are used. Particularly...
- , Z = 26.
Generate one
keystream value for each
letter in the
message using the
keystream algorithm below. Add each
keystream value to the corresponding...

cryptographic known-plaintext
attacks for
breaking stream ciphers whose keystreams are
generated by
combining the
output of
several linear-feedback shift...
- key-autokey
cipher uses
previous members of the
keystream to
determine the next
element in the
keystream. A text-autokey uses the
previous message text...
- authentication. However, it is
quite the reverse. It is
possible to
derive the

Shared Key...
-
partial block of

XORed with the

Coupling with an
efficient keystream generator, such as Panama, MUGI, and RC4, the
