Everything about Adaptive chosen-ciphertext attack

Cryptographic attack

An adaptive chosen-ciphertext attack is an interactive form of chosen-ciphertext attack in which an attacker first sends a number of ciphertexts to be decrypted chosen adaptively and then uses the results to distinguish a target ciphertext without consulting the oracle on the challenge ciphertext. In an adaptive attack, the attacker is further allowed adaptive queries to be asked after the target is revealed. It is extending the indifferent (non-adaptive) chosen-ciphertext attack (CCA1), where the second stage of adaptive queries is not allowed. Wikipedia →

📖 Definitions

Noun An attack on a cryptosystem that relies on the attacker's ability to choose any ciphertext of their liking and decrypt it into the corresponding plaintext with that system and key. More powerful than a chosen-plaintext attack.
