Abstract

This paper presents a fast encryption algorithm for speech signals using the Arnold 3D and the Tent Map chaotic transformations. Arnold 3D chaotic map is known for the property of simultaneously combining pixel scrambling with changing their value in the process of image encryption. The aim of the architecture was to obtain a simple, robust algorithm with short encryption and decryption times, as well as resistant to attacks. All these features make it suitable for real-time communication. The algorithm consists in segmenting the speech signal, then transforming this frame into a cubic three-dimensional structure of samples. The samples are inserted sequentially in vertical slices. Arnold 3D transformation is applied to this structure on horizontal slices, each slice having its own encryption key generated by a Tent Map transformation.
