A Real-time Chaos-based Audio Encryption Scheme.

This work introduces a chaos based audio encryption scheme, along with its implementation, which works in real time. Initially, a novel chaotic map is introduced, and using this map a Pseudo-Random Bit generator is defined. The encryption scheme is defined based on the above and utilizes parallel computing to encrypt recorded audio "on the fly", rather than collecting the complete recording and encrypting afterwards, making the method suitable for real-time encryption. The security of the proposed method is evaluated via statistical tests. Finally, an Open-Source implementation of the proposed method using Python is given.
