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 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.

"WebAnother possible attack is a known ciphertext attack. This time the attacker knows both the plaintext and ciphertext (they simply has to encrypt something). They then try to crack the key to discover the private exponent, d. This might involve trying every possible key in the system on the ciphertext until it returns to the original plaintext.

WebCiphertext-Only (Known Ciphertext) Attack. During ciphertext-only attacks, the attacker has access only to a number of encrypted messages.
