WebAnd this introduces a very significant attack called a padding attack, which we're gonna talk about in the next segment. The solution to this and TLS 1.1, ... One was if the IV is ever repeated and in fact it is gonna be repeated then you get a two time pad attack. And the other problem is that [inaudible] uses very closely related keys. WebThe challenger then encrypts all plaintexts in the set he has chosen, and gives the resulting ciphertexts back to the attacker. The attacker must then guess which of the two sets was encrypted by the challenger. For the two-time pad this attack is very simple: The attacker chooses the plaintext sets ("0", "1") and ("0", "0"). mcelhiney dr cheyenne lmhc
