| Abstract: | The method of differential cipher analysis was presented by E. biham and A. Shamir in 1990. It con-stitutes a realistic threat to DES and DES-like systems. This paper deeply analyzes its principles andpresents seven methods to improve the performance of DES. It is then possible for DES to prevent theattack of differential cipher analysis. |
