| Abstract: | Based on the theory of quadratic forms over finite fields,a new construction of semi-bent and bent functions is presented.The proposed construction has a cascaded characteristic.Some previously known constructions of semi-bent and bent functions are special cases of the new construction. |
| Keywords: | Bent function Semi-bent function Quadratic form |
