A Composition Construction of Bent-Like Boolean Functions from Quadratic Polynomials

Abstract

Boolean functions used in cryptosystems are required to have good cryptographic properties, such as balancedness, high nonlinearity and high algebraic degree, to ensure the systems are resistant against linear cryptanalysis ([2]). Besides, it is a desirable property that a Boolean function has 3-valued spectra. This property provides a protection against… (More)
