WebAug 6, 2024 · In which of the following cryptography attack methods, the attacker makes a series of interactive queries, choosing subsequent plaintexts based on the information from the previous encryptions? A. Chosen-plaintext attack B. Ciphertext-only attack C. Adaptive chosen-plaintext attack D. Known-plaintext attack 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. smart health test
