WebMar 6, 2024 · Types of Cryptanalytic attacks : Known-Plaintext Analysis (KPA) : In this type of attack, some plaintext-ciphertext pairs are already known. Attacker maps them in … WebCryptanalysis refers to the study of ciphers, ciphertext , or cryptosystems (that is, to secret code systems) with a view to finding weaknesses in them that will permit retrieval of the plaintext from the ciphertext, without necessarily knowing the key or the algorithm . This is known as breaking the cipher, ciphertext, or cryptosystem.
