【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。
[Abstract]:With the rapid development of electronic information technology, such as communications and the Internet, and the characteristics of digital content itself, such as easy dissemination and easy reproduction, The digital media content based on the network is more and more accepted and welcomed by the public. However, it is precisely because the digital media content has the characteristics of easy to copy, easy to spread, and poor protection. As a result of widespread duplication and distribution of protected digital media content over the Internet, such piracy and infringement of the authors' intellectual property rights can cause enormous economic losses to the authors concerned. Combating the enthusiasm of digital media content producers hinders the creation of innovative and new content, and hinders the development of the whole economy and culture. In view of these problems, this paper introduces the PKI mechanism into the DRM system. This paper presents a DRM interworking system based on PKI, studies the strategy of the system, and designs the architecture, workflow and key modules of the system. The main work of this paper includes:. Firstly, the basic concept and technical background of DRM are studied, the composition, workflow and existing problems of existing DRM system are analyzed, and the basic concept, architecture and security requirement analysis of PKI architecture are studied. Secondly, aiming at the shortcomings of the existing DRM system mentioned above, this paper gives the whole design requirement analysis, function structure design, work flow and system analysis of the DRM interconnection system based on PKI, and introduces the mechanism of DRM bridge into the system. The problem of interconnection between different DRM devices is solved. Finally, according to the overall functional structure design, the five modules of the system are designed and analyzed in detail, and the design of DRM interworking system based on PKI is completed. In this paper, the DRM mutual operating system based on PKI combines the new technology with the mature DRM technology, and makes full use of the functions of PKI architecture, such as authentication, integrity protection and confidentiality, and through the mechanism of DRM bridge. At the same time, it solves the problems of user privacy and content conversion in the existing DRM system.
