WebJun 9, 2024 · Plaintext Attack. 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. WebApr 24, 2024 · Since Brute Force Attack (BFA) is focused on the key, quantum cryptography is increasing the computation time that BFA require to decrypt an entire set of information because the frequency of key changing in quantum cryptography is increasing more than general cryptography.
