Chaotic QER cryptosystem in the Gaussian number domain

In recent years, applications of chaotic systems in communication and cryptography have attracted much attention. The highly random - look nature and sensitive dependence on initial conditions are the most attractive features of nonlinear systems, which exhibits chaotic behavior [1]. The proposed scheme make use of a new mapping chaotic system using EulerGamma constant, implemented at the transmitter receiver end using the Quadratic-Exponentiation Randomized cryptographic algorithm. The encryption could be done by adding (mixing) the message signal to the output of the chaotic map and the ` the subtraction of a synchronized chaotic map's output from the encoded signal. The encrypted signal would appear to be noise as it has been ldquomixedrdquo with a chaotic signal.
