Secure communication using a modified chaotic masking scheme employing Sprott94 case a chaotic attractor

This paper presents the realization of modified chaotic masking scheme based on the identical synchronization of Sprott94 Case A Chaotic system. This scheme provides an improvement over the basic chaotic masking scheme given by Uyaroglu and Pehlivan in 2010, in the sense that messages of higher amplitudes and lower frequencies can be successfully transmitted with almost no synchronization errors. Numerical simulation shows that the modified masking scheme offer better results in comparison to the basic chaotic masking scheme. Simulations are carried out using Simulink in Matlab environment.
