| Abstract: | The paper proposes a VEA encryption algorithm based on two-dimensional Logistic chaos mapping,namely,to generate two chaos-featured binary key flow sequences with two-dimensional logistics chaotic system equation which are encrypted twice by image DCT coefficients to produce the encrypted image.After their twice encryption by the chaos encryption key,the video data obtain the advantages of high security and strong resistance against attacks. |
