The known-plaintext attack (KPA) is an attack model for cryptanalysis where the attacker has access to both the plaintext (called a crib), and its encrypted version (ciphertext). These can be used to reveal further secret information such as secret keys and code books. The term "crib" originated at Bletchley Park, … See more The usage "crib" was adapted from a slang term referring to cheating (e.g., "I cribbed my answer from your test paper"). A "crib" originally was a literal or interlinear translation of a foreign-language text—usually a See more • Cadix • Cryptanalysis of the Enigma • Kiss (cryptanalysis) • PC Bruno See more 1. ^ Gordon Welchman, The Hut Six Story: Breaking the Enigma Codes, p. 78. 2. ^ Michael Smith, "How It Began: Bletchley Park Goes to War," in B.

WebThe number of bits in a key used by a cryptographic algorithm is referred to as a key size or key length. The key size determines the maximum number of combinations required to break the encryption algorithm, therefore typically a longer key means stronger cryptographic security. answer choices True False Question 9 30 seconds Q.
