| Abstract: | The construction of S Boxes based on genetic algorithm was discussed in this paper, including heuristic mutation strategy, this mutation operation can both prevent destruction of good gene and guarantee diversity of individuals in the population. Under this method, an effective genetic algorithm for 6×6 S Boxes is provided and a number of S Boxes with high non linearity and low difference uniformity can be obtained. |

| Keywords: | S-Boxes non-linearity difference uniformity genetic algorithm heuristic |
