| Abstract: | Two dimensional logistic mapping system with one degree coupled item was defined. The condition and character of the system becoming chaos was discussed. By using digital image encrypting theory, a pixel gray value encrypting algorithm was advanced and realized. The algorithm has filled digital image encrypting requirement by the program and experiment study. |
