In this article, we present a method to synthesize strong nonlinear components used in encryption algorithms. The proposed nonlinear component assists in transforming the intelligible message or plaintext into an enciphered format by the use of Lorenz and Rössler chaotic systems. A substitution box is generated that uses initial conditions, utilize multi-chaotic parameter values, and employ numerical simulations.
