Research on Video Encryption Based on Compound Chaotic System

摘要：

　　Based on the security problem of traditional video encryption algorithm,the compound chaotic map model is used as pseudo-random sequence generator in this paper to generate pseudo-random sequence.A video encryption algorithm based on H.264 standard is designed.First,a new compound chaotic equation is constructed in this paper to generate pseudo-random sequence as the key of this paper.Then,some sensitive data are selected,such as the motion vector difference (MVD),the symbol of MVD and the intra prediction mode.In this paper,the encryption key is analyzed in terms of approximate entropy,information entropy,K entropy and correlation analysis.Experimental results verify that the encryption algorithm has high security.
