摘要

针对视频数据全加密过程中的低效率和只对部分帧加密导致数据泄露问题,采用国密算法SM4逐帧加密H.264格式的I帧、P帧、B帧,同时使用NEON技术加速SM4算法。逐帧加密在防止视频数据泄露方面效果较好,使用NEON之后,SM4加密耗时减少了40%左右。

Abstract

Aiming at the inefficiency in the process of full encryption of video data and the problem of data leakage caused by encrypting only part of the frame,the state secret algorithm SM4 is used to encrypt the I frame,P frame and B frame in H.264 format frame by frame,and the SM4 algorithm is accelerated by NEON technology.Frame by frame encryption has achieved good results in preventing video data leakage.After using NEON,the SM4 encryption time is reduced by about 40% compared that without NEON.
