, Ed. 2:多媒体家用服务器系统.数字版权管理用概念模型

[中文适用范围]： 本技术规范解释了在DRM模块之间交换许可证信息的协议规范的概念模型。本技术规范还概述了哪些模型应定义为标准模型以及标准含义（主要从包括家庭服务器系统在内的环境中的信息安全角度出发）。 [外文原描述]： IEC/TS 62224:2013(E) explains the conceptual model of the protocol specification to exchange license information between DRM modules. This Technical Specification also outlines which models should be defined as standard models as well as the standard meanings (mainly from the viewpoint of information security in the environment, including home server systems). This second edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. It includes the following technical changes: - the Diffie-Hellman method concerning Secure license transaction protocol (SLTP) model has been added, - the Protected Content Format (PCF) model which is dependent on each service has been deleted, - a description related to IEC 62227 has been added, - the classification of certification authority has been added.
