Abstract

Aiming at the problems of small key space and low security of single chaotic system in encryption, this paper proposed a dynamic audio encryption algorithm for image carrier and multi-chaotic system. Firstly, it blocked the plaintext audio to improve the efficiency of the algorithm, generated advanced keys from initial keys and plaintext audio feature values, significantly increasing the key space. This paper designed a random number generator that combined various chaotic systems, and verified its randomness through the NIST sp800_22 randomness test. It transferred the plaintext audio information to the feature matrix P to obtain the audio image. Finally, it obtained the encrypted audio image and encrypted audio through the cyclic remainder scrambling algorithm and diffusion. Simulation experiments and performance tests show that the encryption algorithm has large key space, strong key sensitivity, and uniforms distribution of encrypted audio energy. It has strong anti-attack performance, robustness and efficient encryption efficiency.
