FPGA Implementation of Digital Chaotic Cryptography

In this paper, we present the digital chaotic cryptography implementation on FPGA. The system realization uses AR filter and modulo function as a non - linear component. The hardware implementation of FPGA-based which consumed 288 CLBs has been successfully developed for 24 bits fixed point system using 4-th order filter. The maximum clock frequency used in the experiment is 6.747 MHz.
