Abstract: In the last two decades, cryptography systems based on chaos methods have been developed due to the interesting shared properties between cryptography and chaos systems such as sensitivity to the initial conditions along with the effects of confusion, diffusion techniques. In this study, a seven term new two Dimensional (2D) chaotic system based on two quadratic nonlinear equations has been derived and analyzed. The experimental results and performance evaluations exhibit that the proposed system is capable to generate abundant 2D chaotic maps with expansive chaotic ranges and chaotic manner. The validated chaotic behavior of the proposed system was investigated using maximum Lyapunov exponents, Kaplan-Yorke dimension, phase portraits and sensitivity to initial condition. Furthermore, the generation of chaotic random sequences can be accomplished simultaneously with parallel manner based on two threads which reinforce the speedup performance of the proposed chaotic map generation algorithm. The parallel implementation of the proposed chaotic system using parallel computing library offered by MATLAB equips highly performance than the pipeline ones and would be helpful to utilize in image encryption/decryption with large size.
