Zuo Yan-sheng · Jisuanji gongcheng · 2007
The picture scrambling algorithms based on chaos are frequently used for images secure communications. This computing method harnesses the randomicity and the sensitivity of the original value of the Logistic chaotic sequence, to generate the real value sequence. This paper presents an image encryption technology based on chaotic sequences and fractional Fourier transform. The experimental results show that the technology is valid and has good security.
