| Abstract: | 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. |
| Keywords: | Image Processing chaos encryption VEA Logistic chaotic system equations. |
