A Research on Image Encryption Based on Complicated Chaotic Sequence
Xue Yingxiao · Modern Electronics Technique · 2006
The paper transformed linearly two Logistic maps,and constructed a complicated chaotic system using the boundary property of trigonometric function.In order to improve the randomicity of the complicated chaotic sequence,we analyzed it from the view of cryptology.The result showed that it has excellent randomicity and is adopted as spreading spectrum sequence.In the end,image encryption and decryption with the improved complicated chaotic sequence is studied.
