Summary: In this paper, a novel one-dimensional sine-cosine chaotic map (SCCM) is proposed to overcome the limitations of existing one-dimensional chaotic maps. The superior chaotic performance of SCCM is demonstrated through a series of performance metrics, such as bifurcation diagram, Lyapunov exponent, and approximate entropy. Furthermore, an image encryption algorithm based on SCCM and random DNA operations is presented, which achieves simultaneous row and column indexing dislocation of the plaintext image for better confusion results. The algorithm utilizes random DNA coding and SHA-512 values to enhance security and expand the key space, providing resistance against various attacks and demonstrating good encryption capability.

Summary: This paper proposes a new chaotic system called 2D-HLM, which combines the Henon map and logistic map. Utilizing the SHA-256 algorithm based on the plaintext image, the initial value is generated to enhance the correlation with the plaintext, thereby avoiding vulnerability to selected plaintext attacks. The chaotic sequence generated by 2D-HLM is used to scramble an image, and a novel propositional logic coding algorithm is proposed based on the relationship between two mathematical propositions of the logistic map operations. Simulation results demonstrate that the algorithm possesses a large key space, high key sensitivity, and robustness against common attacks such as differential attack.
