国密算法在数字电影中的应用探讨

A discussion on the application of Chinese national cryptographic algorithms in digital film

为践行《中华人民共和国密码法》中鼓励国家商用密码技术开发和推广应用的精神,对国密算法SM1、SM2、SM3、SM4、SM7、SM9、ZUC的主要特点进行了简要概括,并针对当前数字电影应用场景,对国密算法在数字电影中的应用方案进行了探讨。通过对不同类别国密算法的研究,在数字电影内容加密和传输环节采用国密算法完全可行。本文为数字电影领域国密算法的推广应用提供了可行性支持,有利于加速数字电影关键技术国产化进程。

In order to practice the spirit of Cryptography Law of the Peoples Republic of China,which refers to encouraging development and popularising application towards national commercial cryptography,this paper briefly summarises the main features of Chinese national cryptographic algorithms such as SM1,SM2,SM3,SM4,SM7,SM9 and ZUC,then discusses solutions of Chinese national cryptographic algorithms that are used in digital film for application scenarios now.Through researches towards different categories of Chinese national cryptographic algorithms,the results show that it is completely feasible to use Chinese national cryptographic algorithms in the encryption and transmission of digital film content.This paper provides feasible support for the popularisati-on and application of Chinese national cryptographic algorithms used in digital film,while it may effectively accelerate the timetable for localising key technologies in this field.
