Chaos-like characteristics of pi series and its application to image encryption
Ting Chen, Feng Li · Computer Engineering and Applications Journal · 2008
A new concept of pi series is proposed and its chaos-like characteristics have been found by the method of nonlinear time series.Then a new image encryption algorithm based on pi series is proposed to diffuse pixel positions and confuse pixel values.According to the security analysis,the image encryption algorithm demonstrates strong resistance towards exterior attacks such as statistical attacks and differential attacks.
