An Improved BMP Image Encryption Algorithm Based on Logistic Map
Logistic map is a simple non-linear model, but it has complex dynamics. The chaotic sequence produced by logistic map is extremely sensitive to the change of its initial value. This paper analyzes traditional Logistic chaotic image encryption method, and proposes an improved encryption algorithm. The algorithm produces nine chaotic sequences, six are used to scramble the position of image pixels in red component, green component and blue component, while the others are used to confuse and diffuse image pixels value in red component, green component and blue component. The simulation results show that the algorithm is simple, practical, secure and consumes less calculation time.
