点播影院系统及设备安全级别测试分析

Discussion on Security Level of On-demand Cinema System and Equipment

主要介绍点播影院系统及相关设备安全级别测试的主要内容及相关理论,分别从影片内容加密、影片打包、播放器认证与授权、显示设备链路安全、物理安全及数字水印六个方面对安全级别的测试方法进行分析解读,并对标准中存在的问题及测试过程中发现的一些问题进行了简单的说明。随着相关规范的不断完善,较低安全级别的设备会慢慢地被淘汰出局,点播影院行业也会越来越规范化。

This paper mainly introduces the main contents and related theories of security level testing of on-demand cinema system and related equipment,analyzes and interprets the testing methods of security level from six aspects:film content encryption,film packaging,player authentication and authorization,display device link security,physical security and digital watermarking,and simply explains the problems in the standard and some problems found in the testing process.With the continuous improvement of relevant specifications,the equipment with lower security level will be gradually eliminated,and the on-demand cinema industry will become more and more standardized.
