Abstract

In this paper, we revisit the construction given by Pang et al. in Advances in Mathematics of Communications, 2021, 15(4): 757–775. We simplify the original construction as a product of a Boolean function with a linear function. The relationship between the Walsh transform values of the original Boolean function and those of the resulted Boolean function is established. The virtue of our proposed construction is that it can be generalized to the case of the product of a Boolean function with two linear functions. By using the bent function satisfying property <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{P}_{\tau}$</tex> with a fixed defining set, which was first introduced by Tang et al. in 2017, Boolean functions with five or seven Walsh transform values can be derived.
