| 摘要: |
| 差分密码分析方法是1990年由E. Biham和 A. Shamir提出的，这种方法对DES 算法及DES类体制构成了威胁。本文在剖析了差分密码分析方法工作原理的基础上，提出了改进 DES 算法的7种方法，从而可以有效地阻止差分密码分析法的攻击。 |

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