WebAug 25, 2024 · Abstract. We analyze the security of the Thorp shuffle, or, equivalently, a maximally unbalanced Feistel network. Roughly said, the Thorp shuffle on N cards mixes any N^ {1-1/r} of them in O (r\lg N) steps. Correspondingly, making O ( r) passes of maximally unbalanced Feistel over an n -bit string ensures CCA security to 2^ {n (1-1/r)} queries. WebThe creepiest bill cipher moment ever
