Binary Image Scrambling Scheme Based on Arnold Transformation and Two Chaotic Sequences
Wenlong Wang · Computer Era · 2009
A binary image scrambling scheme based on Arnold transformation and two chaotic sequences is proposed. First Arnold transformation is used to disrupt the logical links between pixels, and the intercepting method is used to get two intermediate sequences from Logistic and Hybrid chaotic sequences discretized, then the two sequences and the image are processed by XOR operation for the purpose of changing pixel value. The simulation results show that the algorithm can effectively achieve binary image encryption and it has more key space. The encrypted image has uniform distribution of pixels and good security.
