WebThe attacker is able to select any plaintext and obtain the corresponding ciphertext through that which is known as an encryption oracle, which is a sort of black box that produces the corresponding ciphertext given any plaintext under the sought-after key, but does not reveal the key itself (i.e. you can't crack it open and just grab the key). WebThe most common definitions used in cryptography are indistinguishability under chosen plaintext attack (abbreviated IND-CPA), indistinguishability under (non-adaptive) chosen ciphertext attack (IND-CCA1), and indistinguishability under adaptive chosen ciphertext attack (IND-CCA2).
