随着经济的发展，信息产业在全球范围内的兴起，版权问题越来越越引起人们的注意，信息安全作为一个新兴的产业发展起来了，人们的生活和工作越来越数字化信息化。同时，人们生活的需要，娱乐产业的影片唱片的版权保护也是越来越普遍，本课题通过研究一种新兴的版本保护方案AACS(Advance Access Content System)及其在BD（Blu-ray Disc)中的应用说细阐述这种新型的数字版权保护方法在实际应用中的实现原理及应用优势蓝光光盘作为新一代的高清影片存储发行标准在全世界范围内为世人所接受，并走进公众领域。然而，由于目前蓝光影片只能在专用的硬件设备上播放，尽管个人电脑可以读取蓝光盘数据，并且电脑硬件也可以显示高清的视频，却不能顺利播放受保护的蓝光影片，特别是在非Windows系统上更为明显。 本文系统地阐述了AACS内容蓝光盘的保护体系的保护机制，尤其是对AACS其在加密方案上及可更新的授权回收管理方面做了一大量的研究工作，并用C++语言对其重要的AES加密算法进行了实现，进而可以正确解密蓝光影片。本文应用高级软件工程思想引入组件流行的插技术完成了对蓝光解密核心技术的封装，通过实现BD_Decryptor对AACS解密规格做了一个进行软件编程实现结合透明解密技术，成功实现了对蓝光BD影片的透明解密过程，使得在Linux非Windows等平台上播放蓝光BD影片成为可能。并且，本文采用优秀的开源GUI库wxWidgets,将蓝光透明解密技术与视频播放技术融合进来，形成一款用户友好的跨平台的蓝光播放软件Bluray-Player，具有相当的研究和应用价值。 本文应用现代软件工程方法，将媒体播放，透明解密，插件技术和GUI界面技术应用起来，是对理论和技术的一次综合的应用。另一方面，Bluray-Player的存在也一定程度上说明了蓝光的保护技术也并非是万无一失的，从而据此在现代软件安全上也提出几点建设性的建议。并且在运行环境需求和资源利用方面都优于现行的唯一BD播放软件PowerDVD，同时，BD_Decryptor也解决了合法用户不能合法复制BD盘的限制，也是对现有工具的一个改进。 AACS做为一种内容保护方案也并非绝对安全的，BD_Decryptor的存在说明了这一问题，本文从BD_Decryptor的工作角度分析了AACS可能存在的安全隐患，主要是在受AACS保护的BD盘片在播放时存在的缺陷，并对AACS在实施上的安全问题提出了几点建设性建议。 |

With the economic development and the worldwide rising of information industry, the copyright issue is getting an increasing attention. The information security develops as an emerging industry, making people's life and work more digitalized and informationized. In addition, it is more and more common that the copyright protection for music and film in the entertainment business needs to be realized. In this paper, a newly designed copyright protection plan AACS (Advance Access Content System) was analyzed, and its application in BD (Blu-ray Disc) illustrated the implementation theory of this newly digital copyright protection method in practical application, and demonstrated that as a new standard for storing and publicating HD Videos, the Advanced Blu-ray Disc was getting a worldwide popularity and stepping into public domain. However, since the present Blu-ray Disc can be run by only specialized hardware, the personal computer is not able to play the under-protected blu-ray discs, although PC can read the data of Blu-ray discs and is capable of showing HD videos, which is more obvious when running on non-windows system. In this paper, it systematically illustrated the protection mechanism of Blu-ray discs with content of AACS, in particular, lots of researches were conducted regarding the AACS encryption scheme and its updatable authorization managements. In addition, by adopting C++ language, the vital AES encryption algorithm was realized, which enabled the correct decryption of Blu-ray discs. In this paper, a module popular plugging technique was introduced through advanced software engineering thinking, so as to finish the packing of core technique of Blu-ray decryption. In order to realize BD_Decryptor to AACS, a corresponding software programming realization integrated with transparent decryption technique was conducted, resulting in successful transparent decryption of BD film, creating the possibility of playing BD film on non-windows platform for example on Linux platform. Through the contemporary software engineering method, the media player, transparent decryption, plug-in technology and GUI interface technique were applied in this paper, which can be described as a comprehensive application theoretically and technically. On the other hand, the existence of Bluray-Player indicates that the bluray protecting technique is not perfectly safe, as a result, a few constructive suggestions regarding present soft security were proposed in this paper. The Bluray-player is superior to the present only BD player-Power DVD in terms of running environment requirements and resource utilization, in addition, the BD_Decryptor also remove limitations that impede legitimate users to copy BD discs. AACS was not perfectly safe as a content protection scheme, which was reflected by the existence of BD_Decryptor. This paper, from the perspective of BD_Decryptor operating, analyzed the potential risks of AACS especially including the drawbacks during playing BD discs under protection of AACS, and proposed few constructive suggestions regarding security issues in AACS implementation. |
