Abstract

Secure transmission of information is an important aspect of modern telecommunication systems. Data encryption is applied in several contexts, whenever privacy is a fundamental aspect, e.g., in modern mobile networks. In this work, a stream cipher based on discrete time nonlinear dynamic systems is proposed. The Henon's map is used to generate a chaotic signal. Its samples are quantized and processed to produce a sequence of data as much uncorrelated as possible. The proposed scheme demonstrates high sensitivity to the parameters of the map as well as to initial conditions. The resulting binary sequence is used to mask the stream of information bits.
