WebIn cryptography, a known-key distinguishing attack is an attack model against symmetric ciphers, whereby an attacker who knows the key can find a structural property in cipher, where the transformation from plaintext to ciphertext is not random. There is no common formal definition for what such a transformation may be. WebThis model and classification is fundamental to any discussion of vulnerability of non-disclosure cryptographic algorithms. The focus in this document is on "known clear message pattern" attacks. This is what good communications protocols should guard against. Other forms of attack are not relevant to the discussion of

Similar attacks can be mounted against other schemes, including the Schnorr [12] and Fiat-Shamir [6] schemes. As noted in the Bellcore announcement, the difficulty of the attack does not depend on the size of the key, unlike traditional cryptanalytic techniques.

A chosen-plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker can obtain the ciphertexts for arbitrary plaintexts. The goal of the attack is to gain information that reduces the security of the encryption scheme. Modern ciphers aim to provide semantic security, also known as ciphertext indistinguishability under chosen-plaintext attack, and they are therefore, by design, generally immune to chosen-pla… http://ijiet.com/wp-content/uploads/2024/05/31.pdf
