| Abstract: | This paper introduces two important specifications for cryptographically strong Boolean functions: the balancedness and the nonlinearity, and studies three methods of yielding balanced Boolean functions with a very high nonlinearity,namely concatenating,splitting and modifying sequences. Finally this paper shows that balanced Boolean functions obtained by modifying sequences achieve a nonlinearity higher than that attainable by any previously known construction methods. |
