Image Encryption Algorithm Based on Extended Chaotic Sequences
Yonghong Zhang · Science Technology and Engineering · 2008
An algorithm that constructs extended chaotic sequence presented, which is applied to digital image encryption.Two extended chaotic sequences are generated based on n-order Bez'ier curve and n-order rational Bez'ier curve, and the sequences have good randomization. With nonlinear dispersion, the integer pseudo-random sequences be can got .The experimental results indicate that the algorithm has good encryption results.An algorithm for encryption and decryption of digital image is gotten.
