A Fast Image Encryption Based on Improved Logistic Map

Abstract

Chaotic map has the properties of pseudorandomness, sensitivity to parameters and initial values, which is beneficial to enhance the performance of encryption algorithm. In the era of 5G business and the Internet of Everything, high reliability and low delay of information on high-speed channels provide good basis for the application of fast image encryption algorithm. In this paper, a fast image encryption algorithm based on the improved chaotic model was proposed by using the multiplicative large integer modulo method to homogenize the Logistic map. In the encryption algorithm, the scrambling and diffusion are processed simultaneously, which makes this scheme own high speed. Simulation experiments and performance analysis show that the scheme is safe and reliable, and can effectively meet the needs of safe image transmission in the network.
