Knownplaintext
Known-plaintext attack, or known-plaintext cryptanalysis, is a cryptanalytic model in which the attacker has access to one or more pairs of plaintext and the corresponding ciphertext produced by a secret key. The goal is to deduce the secret key itself or to decrypt additional ciphertexts produced with the same key.
In contrast to other attack models, such as ciphertext-only (where the attacker only observes ciphertext) and
In practice, modern secure schemes are designed to be resistant to known-plaintext attacks under standard threat
Historically, known-plaintext attacks influenced the cryptanalysis of classical ciphers and early block ciphers, guiding the development
