Corpus analysis for Keystream

  • In this selection, "keystream" usually appears near the end of the sentence. The average example has 21.4 words, and this corpus slice is mostly made up of statements.
  • Around the word, stream, rc4, same, must and twice stand out and add context to how "keystream" is used.
  • Recognizable usage signals include and the keystream is combined and bits a keystream. That gives this page its own corpus information beyond isolated example sentences.
  • By corpus frequency, "keystream" sits close to words such as aami, aat and abada, which helps place it inside the broader word index.

Example types with keystream

The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:

Short example sentences

Description RC4 generates a pseudorandom stream of bits (a keystream ). (10 words)

A one-time pad uses a keystream of completely random digits. (11 words)

The keystream is now pseudorandom and so is not truly random. (11 words)

Longer example sentences

Modern stream ciphers can also be seen, from a sufficiently abstract perspective, to be a form of polyalphabetic cipher in which all the effort has gone into making the keystream as long and unpredictable as possible. (36 words)

Securely using a secure synchronous stream cipher requires that one never reuse the same keystream twice; that generally means a different nonce or key must be supplied to each invocation of the cipher. (33 words)

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. (28 words)

Example sentences (12)

A one-time pad uses a keystream of completely random digits.

A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ( keystream ).

Description RC4 generates a pseudorandom stream of bits (a keystream ).

However, the keystream must be generated completely at random with at least the same length as the plaintext and cannot be used more than once.

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.

In the most common form, binary digits are used ( bits ), and the keystream is combined with the plaintext using the exclusive or operation (XOR).

Klein's attack In 2005, Andreas Klein presented an analysis of the RC4 stream cipher showing more correlations between the RC4 keystream and the key.

Modern stream ciphers can also be seen, from a sufficiently abstract perspective, to be a form of polyalphabetic cipher in which all the effort has gone into making the keystream as long and unpredictable as possible.

Advertentie

Securely using a secure synchronous stream cipher requires that one never reuse the same keystream twice; that generally means a different nonce or key must be supplied to each invocation of the cipher.

Self-synchronizing stream ciphers Another approach uses several of the previous N ciphertext digits to compute the keystream.

The keystream is combined with the plaintext digits one at a time to form the ciphertext.

The keystream is now pseudorandom and so is not truly random.
