| 摘 要： | 本文从实际出发减弱了Ｗｅｂｓｔｅｒ和Ｔａｖａｒｅｓ给出的严格雪崩准则（ＳＡＣ）的限制条件，定义了广义严格雪崩准则，并在不作出实质性“牺牲”的前提下避免了严格雪崩准则的阶数与非线性阶之间的折衷。同时，讨论了满足广义严格雪崩准则的布尔函数性质，结果表明满足严格雪崩准则的布尔函数具有的良好性质得到了很好的继承。

| Abstract: | From practical point of view,the strict avalanche criterion(SAC) introduced by Webster and Tavares is improved.Under the new definition,there exists no trade-off between the order of the generlized SAC and the nonlinear order.At the same time,we discuss the properties of the Boolean functions satisfying the generalized SAC,and those good properties of the Boolean functions satisfying the SAC are shown to be satisfied mostly for the Boolean functions satisfying the generalized SAC. |
