摘要
本文揭示了布尔函数的Ｗａｌｓｈ谱的概率实质，对布尔函数的线性逼近的最佳意义作出了概率解释．并利用Ｗａｌｓｈ谱的概率意义进行了谱分析．考察了谱的运算性质。文中的方法和结论对密码设计和分析都是有用的。
In this peper we give the essence of the probability of the Walsh spectra of Boolean functionsand make explanations on the best significance of the linear approximation of Boolean functions.Moreover we make speCtrum analysis by using the significance of the Probability of Walsh speCtraand consider the Properties of the operations of speCtra. The methods and results in this P8per arevan useful for cryptognphic design and cryptogtaphic analysis
