An Audio Encryption Algorithm Based on DNA Coding and Chaotic System

Abstract

Transferring multimedia files like audio is a common problem with information security. Therefore, various encryption technologies are needed to protect these contents. This paper proposes a new audio encryption scheme that provides a high degree of security. The novelty of this scheme is the use of chaotic systems and DNA coding to confuse and diffuse audio data. The initial value of the chaotic system is controlled by the hash value of the audio, making the chaotic trajectory unpredictable. Comparison experiments using different types of audio show that the algorithm works well and is secure enough to withstand many common attacks and can be recommended for multi-channel audio processing.
