Web1): Achosen-plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker can obtain the cipher texts for arbitrary plaintexts. The goal of the attack is to gain information that reduces the security of the encryption scheme.

The known-plaintext attack (KPA) is a cryptanalysis attack paradigm in which the attacker has both the plaintext (also known as a crib) and its encrypted form (ciphertext). These can be used to uncover more secrets, such as secret keys and codebooks. Known-plaintext attacks are common against traditional ciphers. photo memory book ideas
