This paper presents a secure image encryption algorithm that combines a modified Lorenz-based chaotic system with an adaptive permutation-diffusion architecture. The scheme begins with the chaos-controlled dynamic pixel scrambling through the Arnold Cat Map for enhanced unpredictability. A second phase of XOR-based diffusion, fueled by high-dimensional chaotic sequences, exhibits strong key sensitivity and robustness against statistical and differential attacks. Experimental outcomes confirm the effectiveness of the scheme, which generates high entropy (7.9738).

摘要

This paper presents a secure image encryption algorithm that combines a modified Lorenz-based chaotic system with an adaptive permutation-diffusion architecture. The scheme begins with the chaos-controlled dynamic pixel scrambling through the Arnold Cat Map for enhanced unpredictability. A second phase of XOR-based diffusion, fueled by high-dimensional chaotic sequences, exhibits strong key sensitivity and robustness against statistical and differential attacks. Experimental outcomes confirm the effectiveness of the scheme, which generates high entropy (7.9738).
