一种基于二维Logistic混沌映射的VEA置乱加密算法设计
A Design of the VEA Scrambling Encryption Algorithm Based on Two-Dimensional Logistic Chaos Mapping
摘要
Abstract
A VEA scrambling encryption algorithm design based on two-dimensional Logistic chaos mapping is put forward to deal with the security problem of video information. Firstly we transform the I frame,P frame and B frame of video data by DCT(Discrete Cosine Transform), and scramble the DC and AC coefficients, and then use the two dimensional chaotic sequences of the Logistic chaotic system to encrypt the DC and AC coefi-cients twice, and then we obtain the encryption data. The video data which are encrypted twice by the chaos key have the characteristics of high security, strong attack-resistance and so on.关键词
