This article show a nonlinear dynamical system capable of generating spatial attractors. The main activity is the realization of a spatial chaotic attractor on Xilinx FPGA board PYNQ-Z1 by programming Python used Jupyter, with a focus on the implementation of a secure communication system. The first contribution is the successful synchronization of two chaotic attractors systems, in VHDL program, in a master-slave topology. The second important contribution is the FPGA realization of a secure communication system based on a spatial chaotic attractor, which involves encrypting grayscale and RGB images with chaos and broadcast key in the transmission system, sending the encrypted image through of the state variables and reconstruct the encrypted image then in the receiving system recovers sent imagen.
