华中科技大学硕士学位论文 华 中 科 技 大 学 硕 士 学 位 论 文 II II Abstract With the prospering market of high-defined TV, Blue-Ray Disc wants its share for a long time. If China choosed Blue-Ray to be the standard, a lot of patent fees needs to be payed for each palyer producted by Chinese factory. In this background, NVD, who is totally owned by china, is given birth to in 2006. NVD on Demand system is a new model of playing NVD discs, including four parts: NVD disc, NVD player, management server and certificate server. Its main idea is that users get encrypted high-defined discs from movie providers for free. They request to be granted the key for the disc each time they play the disc.One problem is, how to assure security of NVD on Demand system communiction. NVD on Demand system is facing lots of security defects and threats.NVD on Demand system communication should reach security golas including password security, autnentication etc. As a embedded set, NVD player has limited cpu power and its contents of communication is sually short. Some security mechanisms needed is pointed out. Identity-Based NVD on Demand Seurityy Protocol (IBNODSP) is presented as a solution for communication security of NVD on Demand. It avoids the defects of traditional mechanism and has their goods. IBNODSP presents detailed schemes for identity authentication and private key districution, which are considered to be the two main problems in IBC.The following security services are provided by IBNODSP: authentication between two sides, secure communication, repudiability, resistence against replay atacks,etc. Key words: NVD on Demand, Identity-Based Cryptography, Network security, Communication protocol 独创性声明 本人声明所呈交的学位论文是我个人在导师指导下进行的研究工作及取得 的研究成果。尽我所知，除文中已经标明引用的内容外，本论文不包含任何其他 个人或集体已经发表或撰写过的研究成果。对本文的研究做出贡献的个人和集 体，均已在文中以明确方式标明。本人完全意识到本声明的法律结果由本人承担。 学位论文作者签名： 日期： 年 月 日 学位论文版权使用授权书 本学位论文作者完全了解学校有关保留、使用学位论文的规定，即：学校有权 保留并向国家有关部门或机构送交论文的复印件和电子版，允许论文被查阅和借阅。 本人授权华中科技大学可以将本学位论文的全部或部分内容编入有关数据库进行检 索，可以采用影印、缩印或扫描等复制手段保存
