Adaptive chosen plaintext and chosen ciphertext attack

From Wikipedia, the free encyclopedia

In cryptography, an adaptive chosen plaintext attack and chosen ciphertext attack is one in which the attacker can choose both plaintexts to be encrypted and ciphertexts to be decrypted, and can do so interactively, basing one query on the results of the previous. It combines the capabilities of an adaptive chosen plaintext and an adaptive chosen ciphertext attack. The scenario is one which presumes the greatest capabilities of an attacker, and so is the least likely to be feasible in practice. Two attacks of this type are the yoyo game and boomerang attacks on block ciphers.
