【摘要】：隨著通信、互聯(lián)網(wǎng)等電子信息技術(shù)的高速發(fā)展,以及數(shù)字內(nèi)容本身易傳播、方便復(fù)制等特點(diǎn),基于網(wǎng)絡(luò)傳播的數(shù)字媒體內(nèi)容越來越得到大眾的認(rèn)可與歡迎。但是正是由于數(shù)字媒體內(nèi)容具有易復(fù)制、易傳播、保護(hù)性差的特點(diǎn),導(dǎo)致通過互聯(lián)網(wǎng)復(fù)制傳播受保護(hù)的數(shù)字媒體內(nèi)容的現(xiàn)象十分普遍,這些盜版以及侵犯作者知識(shí)產(chǎn)權(quán)的行為會(huì)給相關(guān)作者帶來巨大的經(jīng)濟(jì)損失,打擊數(shù)字媒體內(nèi)容生產(chǎn)者的積極性,阻礙了創(chuàng)新性和新內(nèi)容的產(chǎn)生.對(duì)整個(gè)經(jīng)濟(jì)和文化的發(fā)展帶來阻礙作用。針對(duì)這些問題,本文將PKI機(jī)制引入DRM系統(tǒng),提出了一種基于PKI的DRM互聯(lián)互通系統(tǒng)。研究了該系統(tǒng)的策略、設(shè)計(jì)了該系統(tǒng)的體系結(jié)構(gòu)、工作流程和關(guān)鍵模塊。 本文的主要工作包括： 首先,研究了DRM的基本概念和技術(shù)背景,分析了現(xiàn)有DRM系統(tǒng)的組成、工作流程以及存在的問題。研究了PKI體系結(jié)構(gòu)的基本概念、體系結(jié)構(gòu)以及安全需求分析。 其次,針對(duì)前文提到的現(xiàn)有DRM系統(tǒng)的缺點(diǎn),給出了基于PKI的DRM互聯(lián)互通系統(tǒng)的整體設(shè)計(jì)需求分析、功能結(jié)構(gòu)設(shè)計(jì)、工作流程以及系統(tǒng)分析。并將DRM橋的機(jī)制引入到系統(tǒng)中來,解決了不同DRM設(shè)備間互聯(lián)互通的問題。 最后,根據(jù)整體功能結(jié)構(gòu)設(shè)計(jì),對(duì)構(gòu)成系統(tǒng)的五個(gè)模塊進(jìn)行詳細(xì)的設(shè)計(jì)以及分析,完成了基于PKI的DRM互聯(lián)互通系統(tǒng)的設(shè)計(jì)。 本文提出的基于PKI的DRM互操作系統(tǒng)將新技術(shù)與成熟的DRM技術(shù)相結(jié)合,充分利用了PKI體系結(jié)構(gòu)的認(rèn)證功、完整性保護(hù)以及保密等功能,并通過DRM橋機(jī)制,在實(shí)現(xiàn)了數(shù)字版權(quán)保護(hù)的同時(shí),又解決了現(xiàn)有DRM系統(tǒng)在用戶隱私和內(nèi)容轉(zhuǎn)換方面的問題。
[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.
