Image encryption is the premises of secret image transmission in network.The paper discusses the characteristics of chaotic sequence and BlumBlumShub generator,and generates position scrambling matrix and coefficient disturbing matrix.Then two matrixes was used to encrypt image DWT coefficient,and experimental results show that the algorithm is fairly good in efficiency and practicality.
