Efficient Colour Image Encryption Algorithm Using a New Fractional-Order Memcapacitive Hyperchaotic System

In comparison with integer-order chaotic systems, fractional-order systems exhibit more complex dynamics. recent years, research into fractional for the utilization of image cryptosystems has become increasingly highlighted. This paper describes development, testing, numerical analysis, and electronic realization a memcapacitor. Then, new four-dimensional (4D) memcapacitive hyperchaotic system is suggested based on this Analytically numerically, nonlinear dynamic properties have been explored, where various methods, including equilibrium points, phase portraits attractors, bifurcation diagrams, Lyapunov exponent, are considered to demonstrate chaos behaviour system. Consequently, an encryption cryptosystem algorithm used colour model, every pixel value original incorporated in secret key strengthen pirate anti-attack robustness. For generating keyspace that employed cryptosystem, initial condition values, parameters, derivative value(s) (q) utilized. The common cryptanalysis metrics verified detail by histogram, keyspace, sensitivity, correlation coefficient entropy, time efficiency, comparisons other related fieldwork order security level proposed approach. Finally, images sizes were encrypted recovered ensure utilized approach capable encrypting/decrypting sizes. obtained experimental results analyses illustrate excellent accuracy, high security, perfect efficiency which highly resistant forms attacks.
