Cryptanalysis of Some Recently-Proposed Multiple Modes of Operation

  title={Cryptanalysis of Some Recently-Proposed Multiple Modes of Operation},
  author={David A. Wagner},
In a paper cryptanalyzing many triple modes of operation, Biham proposed four new triple modes and five new quadruple modes of operation for DES. It was conjectured that the complexity (in a particular threat model) of breaking the triple modes is at least 2 and that the quadruple modes are more secure than any triple mode. We present new attacks on all but one of the proposed modes. We can break all but two of Biham’s proposed modes with at most 2 off-line trial encryptions and between 2 and 2… CONTINUE READING
