| 摘要: |
| 布尔置换在密码体制中有着非常重要的应用。在分组密码的设计中需要用到高阶的布尔置换。论述了一种通过组合一些低阶布尔置换来构造高阶布尔置换的方法，给出了一个例子。所得结论对布尔置换的构造具有一定的意义。 |

| Abstract: |
| Boolean permutations are in very important applications in cryptosystems. In the design of block cipher，those of high degree are needed. In this paper，a method of constructing boolean permutations of high degree by combining some boolean permutations of low degree is provided，and an example is given. The results are useful to the construction of boolean permutations. |
