SPECTRAL CHARACTERIZATION OF BOOLEAN FUNCTIONS SATISFYING k ORDER PROPAGATION CRITERION
-
摘要: 本文首先討論了滿足k次擴散準則的布爾函數(shù)的譜特征;其次探討了滿足k階嚴格雪崩準則的布爾函數(shù)的譜特征;最后引入了廣義e-k次擴散準則的概念,并給出了滿足這種準則的布爾函數(shù)的譜特征。

Abstract: Firtly, spectral characterization of Boolean functions satisfying k order propagation criterion is discussed; secondly, spectral characterization of Boolean functions satisfying k order strict avalanche criterion is described; finally, the generalized e- k order propagation criterion is introduced and its spectral characterization is given. -
