An Image Encryption Algorithm Based on Hyperchaotic Sequences
Yonghong Zhang · Computer Engineering and Science · 2008
The paper gives an algorithm for generating extended chaotic sequences,and the extended chaotic sequences are applied to digital image encryption.The algorithm is based on the n-order rational Bezier curve,and the generated sequences feature good randomization.With a nonlinear discretization of the sequences,we can get the relevant integer pseudo-random sequences.The experimental results indicate the algorithm has good encryption effect in encrypting and deerypting digital images.
