基于PKI的DRM互操作系统的研究与实现
摘要
随着通信、互联网等电子信息技术的高速发展,以及数字内容本身易传播、方便复制等特点,基于网络传播的数字媒体内容越来越得到大众的认可与欢迎。但是正是由于数字媒体内容具有易复制、易传播、保护性差的特点,导致通过互联网复制传播受保护的数字媒体内容的现象十分普遍,这些盗版以及侵犯作者知识产权的行为会给相关作者带来巨大的经济损失,打击数字媒体内容生产者的积极性,阻碍了创新性和新内容的产生.对整个经济和文化的发展带来阻碍作用。针对这些问题,本文将PKI机制引入DRM系统,提出了一种基于PKI的DRM互联互通系统。研究了该系统的策略、设计了该系统的体系结构、工作流程和关键模块。
本文的主要工作包括：
首先,研究了DRM的基本概念和技术背景,分析了现有DRM系统的组成、工作流程以及存在的问题。研究了PKI体系结构的基本概念、体系结构以及安全需求分析。
其次,针对前文提到的现有DRM系统的缺点,给出了基于PKI的DRM互联互通系统的整体设计需求分析、功能结构设计、工作流程以及系统分析。并将DRM桥的机制引入到系统中来,解决了不同DRM设备间互联互通的问题。
最后,根据整体功能结构设计,对构成系统的五个模块进行详细的设计以及分析,完成了基于PKI的DRM互联互通系统的设计。
本文提出的基于PKI的DRM互操作系统将新技术与成熟的DRM技术相结合,充分利用了PKI体系结构的认证功、完整性保护以及保密等功能,并通过DRM桥机制,在实现了数字版权保护的同时,又解决了现有DRM系统在用户隐私和内容转换方面的问题。
With the rapid development of communication, the Internet and other electronic information technology, as well as the digital content itself is easy to spread facilitate replication characteristics, the spread of network-based digital media content has been more public recognition and welcome, especially the PC and the popularity of smart phonesso that the people can enjoy the convenience of digital content anywhere, anytime. But it is easy to copy, easy to spread, and protective digital media content, the copy is widespread dissemination of protected digital media content via the Internet, of these piracy as well as acts of infringement of intellectual property rights by the author will give relevant of bring huge economic losses, of combating digital media content producers actively hinder innovation and the generation of new content, hindering the development of the entire economic and cultural.
The main works of this paper are as follows:
Firstly, the study of the basic concepts and technical background of the DRM, the analysis of the composition of the existing DRM system, workflow as well as problems. Study the basic concepts of the PKI architecture, architecture, and security needs analysis.
Secondly, for the shortcomings of existing DRM systems previously mentioned, given based on PKI DRM interoperability needs of the overall design of the system analysis the functional structure design, workflow, and system analysis. And DRM Bridge mechanism is introduced into the system to solve the problem of interoperability between different DRM device.
Finally, based on the overall function of structural design, detailed design and analysis, completed to constitute a system of four modules based DRM interoperability PKI system design.
PKI-based DRM interoperable system of new technology and mature DRM technology combine to take full advantage of the power of the PKI architecture certification integrity protection and confidentiality, by DRM bridge mechanism, digital rights protection while existing DRM system is to solve the problem of user privacy and content conversion.
