- Bent function plays an important role in cryptography. It opposes an optimum resistance to linear and differential cryptanalysis. We point out that for some kinds of bent functions, such as Maiorana-McFarland functions and functions with algebraic degree less than three, they are weak in second-order differential cryptanalysis. Thus when constructing bent functions we should use other methods and avoid these functions. Furthermore, a bent function can split into four bent pieces if and only if, the corresponding second-order differential of its dual function is 1.
