Webtions systems that represent known-plaintext attacks (KPA) on the Small AES-64 model cipher. The KPA is an attack model of cryptanalysis where the attacker has access to both the plain-text and its encrypted version (ciphertext). Knowing the cryptographic algorithm, the goal of the attack is to reconstruct the secret key from the text information.

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").
