Abstract

In recent years, as video technologies have been broadly used in TV, communication and multimedia, video security has been gaining in importance. This paper proposes a real-time selective video encryption using context-key control. The new context-key control encryption in this scheme is modified from ElGamal encryption. Using context-key control, our scheme can perform a low exponent operation and secure encryption. We apply our encryption scheme to perform selective encryption on video DCT coefficients. In our performance and security analysis, our scheme is a secure and efficient video encryption scheme, and can be well applied to the video protection.
