摘要
提出了一种利用混沌理论加密MPEG-2视频文件的方法。通过综合应用实值混沌序列加密,幻方矩阵置乱和符号矩阵加密3种方法对视频信息进行加密,并将加密结果与单独应用以上3种方法的加密结果进行了比较,并比较了这种方法相对于椭圆曲线公钥加密算法对视频信息进行加密的优点。
An approach of utilizing the chaos encryption to encipher MPGE-2 videos is proposed. Three methods of real-valued chaotic sequence, magic square and sign matrix are synthetically employed in video encryption. The result of using the three methods is compared with one of the results using these methods separately. The advantages of this method compared with that using Elliptic Curve Cryptosystem (ECC) are presented.
