Image Encryption Algorithm Based on Logistic Chaotic Scrambling System

摘要

In order to ensure the confidentiality of image in transmission, a two-dimensional Logistic chaotic system with wide key space is constructed, which integrates with the random scrambling encryption algorithm, and scrambles the original image by optimizing the discrete chaotic sequence to form the encrypted image. The simulation results show that the algorithm is easy to implement, highly efficient, sensitive to the initial condition disturbance of the system, and it has large key space, good security and strong anti-attack ability.
