| Popis: | A novel image encryption algorithm that based on Erbium-doped fiber laser with an optical delay feedback (ODF-EDFL) system is proposed in this paper. First, by the dynamic analysis of this system, two different chaotic sequences are generated. Meanwhile, the statistic characteristic is verified on this chaotic sequence. On this basis, the image encryption algorithm is designed by using this chaotic sequence: the gray value of the original image is substituted with the chaotic sequence at beginning; then the space array of the image's pixel is mixed up by using both two chaotic sequences. The experimental results show that the proposed method can encrypt digital images quickly and effectively. |
