Abstract

H.264 video coding standard supports a broad range of application,and how to guarantee its security has already become an urgent problem. In this paper, we propose a video encryption algorithm for H.264, which combines stream cipher algorithm with entropy coding process. It obtains video content security by encrypting codeword index to scramble the position of the codeword. Experiments show that, the proposed algorithm is able to provide compromise between security and complexity, has little effect on compression performance. It's believed to be applied in the fields of video conference, digital rights management, multimedia storage, etc.
