| Abstract: | By using chaotic sequence and symmetric block cipher scheme named ZF-02, a new scheme of digital image scrambling is proposed. The chaotic sequence is applied to give original cipher, which can control complex transposition permutations of input and output. The cipher algorithm of ZF-02 can resist several attacks effectively and can be realized easily by both software and hardware. |
