Image encryption based on Logistic-Sine self-embedding chaotic sequence

Abstract

In this article, for the security of image transmission, we present a novel image encryption algorithm based on Logistic-Sine self-embedding (LSSE) chaotic sequence. Firstly, we verify the effectiveness and superiority of the chaotic map by using a variety of indicators such as the Lyapunov exponent, bifurcation diagram, and 0-1 test. The chaotic key is combined with Arnold scrambling transformation to scramble the image, to break the high correlation between image pixels. Then, the image is diffused based on LSSE. The robustness and effectiveness of the proposed method are verified by various computational tests, and the scheme is analyzed using the performance indicators of histogram distribution, correlation, key sensitivity, attack test, and comparison with other algorithms. The computational experiments show that the algorithm has excellent performance and adequate security.
