摘要

对OMA、微软、Intertrust、ChinaDRM等不同DRM标准进行特点和差异性比较，提出DRM应用的需求场景，分析了DRM关键技术，基于业界普遍使用的高安机顶盒对IPTV高清视频领域DRM保护需求进行架构设计，创新性地提出了高安机顶盒的硬件信任根、远程下载终端密钥、双重加密的内容密钥，能够充分利用目前机顶盒生产过程中已有的芯片OTP数据烧写流程，既充分考虑运营中的可实施性，又保障了DRM安全性，最后制定了DRM内容解密的业务流程并给出实施案例。

Abstract

The characteristics and differences of different DRM standards such as OMA

Microsoft

Intertrust

and ChinaDRM were compared.The requirements of DRM applications were presented.The key technologies of DRM were analyzed.Based on the high-tech set-top box commonly used in the industry

the architecture of DRM protection in IPTV high-definition video was designed.The hardware trust root of high security set-top box

remote download terminal key

double-encrypted content key and other mechanisms was put forward innovatively.Finally

the business process of decrypting DRM content was formulated and an implementation case was given.
