This paper, we examine one such attempt, the method of differential cryptanalysis, published by Biham and Shamir. We show some of the safeguards against differential cryptanaiysis that were built into the system from the beginning, with the result that more than bytes of chosen plalntext are required for this attack to succeed."</ins></div></td></tr>
