Abstract With the increasing popularity of multimedia data on the internet and our daily life, the way people get information is becoming more diverse, video is becoming an important part of our dailylife and work. At the same time, the popularity of video also brings new security risks and challenges, more and more people are paying attention to video security issues. Based on hyperchaotic system, this paper proposes and implements a video encryption scheme. The encryption algorithm divide a video stream into a color image stream and an audio stream. Color image is composed of three-dimensional channels of Y, Cb, and Cr, the amount of practical information carried by three channels is different. Therefore, an Anorld transforms and a DNA encoding algorithm is used for the Y channel with more information. The Cb and Cr channels with less information are encrypted by Lorenz hyperchaotic map. Audio information is encrypted by Logistic chaotic map. The paper thoroughly tested the feasibility of the process of encryption and decryption, analyzed the resistance of statistical attacks and completed tests on the histogram, information entropy, and correlation of neighboring pixels. The paper also tested the scheme’s ability to resist violent attacks and completed the analysis of key space, key sensitivity, signal-to-noise ratio, spectrogram, variance, and mean. At the end of the article we test the comparison of capability and efficiency of our scheme and other two methods. Results of experiment show that our scheme has better security and encryption efficiency. Keywords Video encryption · Audio encryption · Hyperchaotic
1 Introduction With the vigorous development of computer science and network technology, multimedia data is gradually popularized and applied to the network and people’s daily life. However, due to the openness and anonymity of the network, digital TV, video-on-demand, video calls, and other video streams are vulnerable to be attacked. In recent years, the security of video files has become a hot research. Lian et al. [6, 18]. Xin Jin

Several media information encryption algorithms have been proposed in recent years. In 2018, Li and others propoesd a selective encryption scheme with a chaotic encryption system for the high efficiency video coding (HEVC) standard in which context adaptive binary arithmetic coding (CABAC) is the only entropy coder for transform coefficient coding. In 2019, Li Hao and others [3] proposed a cloud-fog-local video encryption framework which consists of a three-layer s
