What (who) is chosen plaintext attack - definition

CRYPTANALYTIC ATTACK MODEL IN WHICH THE ATTACKER CAN OBTAIN THE CIPHERTEXTS FOR ARBITRARY PLAINTEXTS
Chosen plaintext; Chosen-text attack; Chosen-plaintext; Adaptive chosen-plaintext attack; Adaptive chosen plaintext attack; Chosen plaintext attack; Chosen plaintexts; Plaintext injection; Known-plaintext injection; Known plaintext injection

Chosen-plaintext attack         
A chosen-plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker can obtain the ciphertexts for arbitrary plaintexts.Ross Anderson, Security Engineering: A Guide to Building Dependable Distributed Systems.
Adaptive chosen-ciphertext attack         
INTERACTIVE FORM OF CHOSEN-CIPHERTEXT ATTACK IN WHICH AN ATTACKER FIRST SENDS SOME CIPHERTEXTS TO BE DECRYPTED CHOSEN ADAPTIVELY AND THEN USES THE RESULTS TO DISTINGUISH A TARGET CIPHERTEXT WITHOUT CONSULTING THE ORACLE ON THE CHALLENGE CIPHERTEXT
Adaptive chosen plaintext and chosen ciphertext attack; Adaptive chosen ciphertext attack; Adaptive-chosen-ciphertext attack; CCA-2; Bleichenbacher’s attack
An adaptive chosen-ciphertext attack (abbreviated as CCA2) 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 (but the target query is disallowed).
Plaintext-aware encryption         
Plaintext-awareness; Plaintext aware; Plaintext awareness
Plaintext-awareness is a notion of security for public-key encryption. A cryptosystem is plaintext-aware if it is difficult for any efficient algorithm to come up with a valid ciphertext without being aware of the corresponding plaintext.

Chosen-plaintext attack

A chosen-plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker can obtain the ciphertexts for arbitrary plaintexts. The goal of the attack is to gain information that reduces the security of the encryption scheme.

Modern ciphers aim to provide semantic security, also known as ciphertext indistinguishability under chosen-plaintext attack, and they are therefore, by design, generally immune to chosen-plaintext attacks if correctly implemented.
