Chaotic systems have been shown to have interesting properties for the generation of spreading sequences in various spread-spectrum applications. The aim of this paper is to exploit the topological features of a time-delay system with appropriate non

In this paper, we exploit the topological features of nonlinear delay differential systems (NDDS) to study the statistical performance analysis of a cryptosystem based on the discretized version of a simple first order time-delay system with appropri
