Abstract
The manuscript analyzes fractional order chaotic cryptovirology in blockchain using various methods in dynamics such as Lyapunov exponents, stagnation points, symmetry, bifurcation diagrams etc. The internet is the most powerful tool that has changed every aspect of living. But this internet has also become primary medium of cyber-crime. The dynamics of the modeled system for variable fractional order between 0.8 to 1 is also observed. The chaos in the studied dynamical system is controlled about its two stagnation points using SMC controllers assuming uncertainties and disturbances.
