Electronics and Cryptography with Fractional Derivative Memristor based 4D Chaotic Flow

This research study presents a new tangent-hyperbolic memristive based 4D fractional order nonlinear chaotic system. With three memristors and different fractional order index, complex chaotic system is formed which modify the trajectories and increase the complexity. The basic key proposal is to investigate the novel 4D chaotic system, attached with tangent hyperbolic memristors, explore for different values of Caputo fractional derivative, probed with different graphical illustrations, and analysed with mathematical tools like Lyapunov exponents and bifurcation technique. Owing to the distinctive nonlinear chaotic features of the memristor fused with fractional calculus, different random data are generated, which are utilized to execute encryption. Novel algorithms of steganography and watermarking is presented along with the correct and incorrect keys demonstration to secure the data. A complex electronic circuity is designed on MULTISIM and presented to compliment the theoretical outcomes with experimental results.
