基于H.264 SVC的视频分层加密算法研究
ON STRATIFIED VIDEO ENCRYPTION ALGORITHM BASED ON H.264 SVC STANDARD
摘要
Abstract
With the permeation of scalable video encoding ( SVC) , security problems pertinent to scalable video attract growing attention too. Most of the existing encryption algorithms are designed for H. 264/AVC standard, which are not suitable to scalable video encoding. And in this paper we analyse the new use of the techniques of SVC, and take the lead in proposing a new stratified encryption scheme in light of its characteristics. The scheme chooses some key video information different from the usual ones as the objects to encrypt, such as the motion vector of inter-layer prediction and the key frames with SNR scalability,etc. The algorithm is designed according to the types of the information chosen and in combination with the security level the users required. Experimental results show that the new scheme has the advantages in better encryption effect, smaller key volume and higher real-time, and can fit application occasions with different security requirements.关键词
