摘要
本文提出了一种基于混沌密钥的VEA加密算法设计,即通过Logistic混沌系统方程,产生加密的二进制密钥流序列,与图像DCT转换后的DCT系数进行加密,得到加密图像。通过使用混沌密钥进行加密的视频数据,具有安全性高、抵抗攻击能力强等特点。
A VEA encryption algorithm design based on chaos key was proposed in this paper, namely got the encryption binary key stream through the Logistic chaos system equation, and encrypted the DCT coefficients which were transformed from the image DCT, then obtained the encryption image. The video data encrypted by the chaos key has the characteristics of high security, strong attack-resistance and so on.
