摘　　要：近年,随着大数据时代的到来,人类采取的文件加密方式不断进步,从战争时期的摩尔斯电码到如今的各种加密算法,都是为了保护文件的安全性。视频作为承载着各种重要信息的载体,但同时也是数据泄露的高发区,一直需求一个较为安全的保护环境。针对这样的情况,提出一种基于国密算法SM2的视频文件加解密方法。国密算法是我国自主知识产权的商业密码算法,满足电子认证服务系统、重要文件加密等应用需求。In recent years,with the advent of the era of big data,the file encryption methods adopted by human beings have continued to progress,from Morse code during the war to various encryption algorithms today,all in order to protect the security of files.As a carrier carrying all kinds of important information,video is also the hardest hit area of data loss and data copyright,and has always released a strong signal of desire for data security to the outside world.In view of such a situation,this paper proposes a video file encryption and decryption method based on the national secret algorithm.National secret algorithm is China's independent intellectual property rights of commercial cryptography algorithm,SM2 belongs to the asymmetric algorithm,based on elliptic curve cryptography public key cryptography algorithm standard,to meet the electronic authentication service system,important document encryption and other application needs.
