Research on a chaotic image encrypted approach
Qiu Shui-sheng · Journal of China Institute of Communications · 2003
In this paper the technologies of the wireless secure communication and the nonlinear transformation are used. Based on it a hyperchaotic masking and chaotic encrypted method is developed. The hyperchaotic signal is used because of its high complexity,high randomness and unpredictable. The simulation shows that the ciphertext's encryption effect is well,and the recovered image is less different from the original image.
