Boolean functionsA C 0Attribute noiseClassification noiseWe study a procedure for estimating an upper bound of an unknown noise factor in the frequency domain. A learning algorithm using a Fourier transformation method was originally given by Linial, Mansour and Nisan. While Linial, Mansour and ...
Two functions are complementary if one function equals 1 when the other function equals 0 and vice versa. The complement of a function can be found by complementing each literal in the dual of that function. Thus the complement of f(A, B, C, D) = ABC¯ + CD + B¯ is f¯(A...

摘要: Bent functions, which are maximally nonlinear Boolean functions with even numbers of variables and whose Hamming distance to the set of all affine functions equals 2n 1±2n 2 1, were introduced by Rothaus in 1976 when he considered problems in...

The functionboolcreturns a single-character character string of the typestring. If the logical expression is true, "X" is returned. If the logical expression is false, a blank is returned. In principle,boolcis one of theprocessing functions with character-like resultsand can be specified ingen...
With cryptographic investigations, the design of Boolean functions is a wide area. The Boolean functions play important role in the construction of a symmetric cryptosystem. In this paper the modified hill climbing method is considered. The method allows using hill climbing techniques to modify bent ...
In this paper, we study Boolean functions of an odd number of variables with maximum algebraic immunity. We identify three classes of such functions, and give some necessary conditions of such functions, which help to examine whether a Boolean function of an odd number of variables has the maxi...
Christoph Scholl 364Accesses Abstract The first chapter gives basic definitions and notations for Boolean functions. These notations will be used in the following chapters. The main representations for Boolean functions introduced in this chapter are Ω-circuits (which are simply circuits based on a ce...
