Robust hardware-supported chaotic cryptosystems for streaming commutations among reduced computing power nodes

Resumen

Most recent technological proposals, such as Cyber-Physical Systems or Wireless Sensor Networks, consist of a collection of tiny nodes designed to be seamless integrated into daily living objects. These nodes then, due to their miniaturized configuration, use to present very limited processing capabilities. Because of that, in general complex algorithms, as which are employed today to secure communications, cannot be implemented in these new systems. Thus, new instruments for security are needed, with a special mention to hardware-supported solutions. Therefore, in this paper different robust hardware-supported cryptosystems based on Chua’s circuit are proposed, studied ad compared. The described solutions are specifically designed to be employed in streaming communications among reduced computing power nodes. Moreover, an experimental validation is proposed comparing the performance of the proposed technologies and other existing solutions.
