Video File Encryption and Decryption System Based on Domestic Algorithm SM2
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 be-longs 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.
