Dear editor,Boolean bent functions were introduced by Rothaus in 1976 as an interesting combinatorial object with the important property of having optimal nonlinearity[1].Since bent functions have many applications in sequence design,cryptography and algebraic coding,they have been extensively studied during the last thirty years[2,3].Over the past decades,based on bent functions,several constructions of highly nonlinear balanced functions were presented[4,5].
