With the development of network and large-scale use of videos in the network,the security of videos becomes one of the important problems. Video encryption proves itself to be a good method this problem. This paper analyzes the scalable coding technologies adopted in H.264/SVC. According to the characteristics of the scalable video coding(SVC),some key information units are selected for encryption. And scalable video encryption is used to achieve different levels of video security. Meanwhile,stream cipher encryption is also used to achieve fairly high security. The experiments show that the proposed scheme is of high security,moderate complexity,and real-time performance.
