An Audio Data Encryption with Single and Double Dimension Discrete-Time Chaotic Systems

Abstract

— In this article, a study on increasing security of audio data encryption with single and double dimension discrete-time chaotic systems was carried out and application and security analyses were executed. Audio data samples of both mono and stereo types were encrypted. In the application here, single and double dimension discrete-time chaotic systems were used. In order to enhance security during encryption, a different method was applied by also using a non-linear function. In the chaos based application realized with the method developed, analyses results were achieved with common security analyses such as key space, key sensitivity, chaos effect and histogram. Several examinations on the safety of chaotic systems in the application were carried out with these analyses results

Keywords
