| 摘 要： | 基于混沌序列的视频加密正在成为热点,提出了很多基于混沌序列的视频加密算法.针对H.264的特点,提出了一种Logistic混沌序列与幻方矩阵结合的视频加密改进算法,Logistic混沌映射产生的混沌序列作为加密序列,同时序列大小顺序编号排列成的幻方矩阵加密DCT非零系数.这种加密算法具有很高的实时性,加密可以和编码并行执行.

| Abstract: | According to the features of H. 264, this paper proposes a video encryption resolution, which is combined of Logistic chaotic sequence and magic square matrix. In this paper, Logistic chaos map chaotic sequence as an encrypted sequence, and sequence size order numbers are made into a magic non - zero matrix encrypting DCT coefficients. This encryption resolution has a high real time, encryption and encoding can be executed in parallel. |
