History abounds with … WebCiphertext-Only (Known Ciphertext) Attack. During ciphertext-only attacks, the attacker has access only to a number of encrypted messages. He has no idea what the plaintext data or the secret key may be. The goal is to recover as much plaintext messages as possible or (preferably) to guess the secret key. After discovering the encryption key ...

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.
