摘要
研究了满足严格雪崩准则布尔函数的性质,证明了雪崩布尔函数的汉明重量只能为偶数,并且得到了雪崩布尔函数的汉明重量之集,给出了不同汉明重量的雪崩布尔函数的构造方法。改进了雪崩布尔函数个数的下界。
Properties of Boolean functions satisfying the Strict Avalanche Criterion（SAC） are studied. It is proved that the Ham- ming weights of SAC functions are even numbers. And the set of Hamming weights of SAC functions is obtained. A new meth- od of constructing SAC functions with different Hamming weights is proposed. The lower bound of the number of SAC func- tions is improved.
