| English Abstract | 通过对代数次数增加情况的分析,研究了type-1广义Feistel结构下,单SP(sub stitution-permutation)模型与双SP模型抵抗高阶差分分析的能力.结合高阶积分与高阶差分思想,开发了四路type-1广义Feistel-SP与Feistel-SPSP结构代数次数上界估计的新方法.利用这一方法,分别构造了这2种结构在2种常用参数下的区分器.结果显示,四路type-1广义Feistel结构下,双SP模型抵抗高阶差分攻击的能力不如单SP模型. |

| Abstract | The powers against the higher-order differential cryptanalysis of the single-SP(substitution-permutation) model and the double-SP model are studied in the type-1 Feistel network by analyzing the growths of algebraic degrees. Combining the higher-order integral and the higher-order difference, a new method is exploited to estimate the upper bounds of algebraic degrees for the 4-line type-1 Feistel-SP scheme and the 4-line type-1 Feistel-SPSP scheme. Applying the new method, distinguishers of the two schemes are constructed with four common parameters. As a result, the double-SP model is weaker than the single-SP model against the higher-order differential attack under the 4-line type-1 Feistel structure. |
