| Abstract: | Cryptographic properties of Boolean functions satisfying PC(k) are considered in this paper.The necessary and sufficient condition of Boolean function such as f(x) g(y) h 1(x)h 2(y) satisfying PC( k ) is given,and new constructions of Boolean functions satisfying PC( k ) are also derived. |
