Design and implementation of synchronized VHDL Lorenz chaotic encryption system

Abstract

This paper focuses on the synchronization of two 3D chaotic systems, when they are connected, using a variable time delay channel then applying the proposed technique for secure communication, and realizing it using VHDL. The results reveal that signals to chaos ratio of -248 dB and synchronization have been achieved. Performance analysis have been conducted to investigate the robustness of the encryption system against different types of attacks.
