Varieties of Chosen-ciphertext Attacks
Chosen-ciphertext attacks, like other attacks, may be adaptive or non-adaptive. In a non-adaptive attack, the attacker chooses the ciphertext or ciphertexts to decrypt in advance, and does not use the resulting plaintexts to inform their choice for more ciphertexts. In an adaptive chosen-ciphertext attack, the attacker makes their ciphertext choices adaptively, that is, depending on the result of prior decryptions.

“We are seeing an increasing level of attacks on the “selfishness” of women. There are allegations that all kinds of social ills, from runaway children to the neglected elderly, are due to the fact that women have left their “rightful” place in the home. Such arguments are simplistic and wrongheaded but women are especially vulnerable to the accusation that if society has problems, it’s because women aren’t nurturing enough.”
—Grace Baruch (20th century)
