Real-time Fpga Implementation Of A Switching Chaotic Generators For The Secure Embedded Systems

This article proposes a new chaotic key generator for data encryption and its optimized FPGA implementation based on a chaos switching rule between Lorenz’s and Lü’s no-linear systems. The originality of our approach is that allows a better security communication for embedded application while provides a good tradeoff between performances and hardware resources. Our experimental results have demonstrated the feasibility and the efficiency of our secure solution on Xilinx FPGA Virtex technology.
