A comprehensive research has made in the application of elliptic curve based bilinear mapping in the group signature, security of bilinear mapping is established on the GAP group. Because the DDH problem is easy to solve in GAP, this fact results it is very difficult to design a bilinear mapping based group signature scheme which can satisfy anonymity and the tractability.

对基于椭圆曲线的双线性映射在群签名中的应用进行了深入的研究，由于双线性映射的安全性建立在GAP群上，而在GAP群上的DDH问题是容易求解的，这样导致在基于双线性映射的群签名方案设计中很难同时兼顾群签名的匿名性和可跟踪性。

All in all, My dissertation mainly focuses on phenomena existing in Chinese venture capital investment market with double principle-agent theory. According to actual conditions, we think that shareholders who are full of wishes to supervise the daily management of the venture capital should be nurtured. Another, the evaluation system with government as cautioner, the incentive and restrictive mechanism implemented and anonymous assess as trait in the beginning of process should be improved uninterrupted. Last but not least, in the choosing of exit ways of the venture capital, the MBO method is one that couldn't be ignored.

并在探究两层委托代理互动关系的基础上，针对我国风险投资市场委托代理中的主体缺位、政策滞后等问题，提出要明确风险投资领域宏观与微观环境建设的政府责任与企业责任：在风险资本市场，要大力宣传和鼓励以民营资本为代表的积极股东的参与；在风险投资项目评估中，应当不断完善以政府担保为主体的、贯彻激励约束机制的、以专家匿名评审为特点的项目评估体系；在风险资本退出模式中，我们强调要更加重视MBO方式对风险投资事业的积极作用。

At the same time, Yin Zhaohui builds up a secret space with close-up body fragments to consolidate his position as a doomster. Those dead-like, anonymous, imperfect figures entangle in a new relationship of desire, which is enormously merciless and painful.

作为审判性观察者的尹朝辉所营造的「私室」，透过没有内容的器官逐渐从虚无中捏造新的欲望关系，自纠结的手指、略露出颜面的肖像、到最后带有残缺感的匿名身体，强调了欲望中所有负面的情绪，是艺术家将自我痛感和清晰明白意念暴露于自我身体和知觉之外的严肃冒险。

In this paper, by considering the convenience of consumers, we use group blind signature technology with the character of hash chain to create the dividable and anonymous e-cash. Thus the users can consume not only in the home mobile domain but also visit mobile domain without register and authentic. We use off-line e-cash to increase the efficiency of payment exchange. Under the fair principle of all participators, we set a convenient and secure mobile payment.

因此，以消费者使用上的最大便利性为考量，本研究利用群体盲签章加入杂凑链之特性的方式来产生可分割的匿名电子现金，让消费者不只可以在主系统业者的网域内作消费，当其到漫游业者的网域内消费时，也不需要额外的认证及注册过程，并采用离线验证的方式来增加付款交易的效率性，在考虑各角色公平的原则下，提供一个方便、安全的行动付款系统。

In this paper, we have proposed a flexible encryption blocks selection buyer-seller watermarking protocol integrated the RSA asymmetric encryption system and homomorphism mechanism to protect the ownership of digital contents and fit real life. And consider the secondhand transaction in the real life. We also propose a buyer-reseller watermarking protocol based on the flexible encrypt blocks selection buyer-seller watermarking protocol to offer a solution of secondhand transaction. In our scheme, it's more light data transport requirement than other schemes. All roles in protocol will benefit by their participation. Our scheme can overcome various of the known attacks and security problems in the buyer-seller watermark protocol, such as buyer's right problem, unbinding problem, piracy tracing problem, conspiracy problem, buyer's participation in the dispute resolution problem, man-in-the-middle attack problem and anonymous problem. Furthermore, the seller and arbiter can verify the buyer's watermark without decrypting it in our scheme.

本文除应用RSA非对称式加密与秘密同态机制，提出了一个符合现实生活中买卖交易行为、可弹性调整加密范围数位内容买卖浮水印协定，强化了目前研究中对於数位内容买-卖浮水印协定的安全性，并进一步的考量二手商品交易行为，在可弹性调整加密范围数位内容买卖浮水印协定基础上，提出一个结合数位内容二手买卖与盗版追踪的二手数位内容买卖浮水印协定，达到让参予买卖的角色可以在安全的情形下完成二手数位内容所有权的移转并从中获取相对应利益的目标的数位内容转卖浮水印协定来增强了目前数位内容买卖浮水印协定研究中对於二手交易欠缺之处，解决了数位内容买卖浮水印协定中所可能遭遇的重要安全性议题，如：买方权益、盗版追踪、资讯不连结、共谋、买方需要参与仲裁、中间者攻击及匿名性问题。

The packed planes imply a cramped space (as John Locke's "Private Room of Mind"), either overly lit or too dim because of camera flash, and the observer behind the camera. The flat square disarranges the domain allotment between subject and object or the observer and the observed. The lack of depth gives the observer a superior status as a judge in a secretive trial that has been carefully arranged by the artist. The scene provokes a lot of doubt in the mind of the audience and they feel they are exiled.

尹朝辉的作品多以拥挤的画面象征忧郁狭小的房间（暗喻洛克John Locke的「心灵所在的私室」），光线过亮或不足、强烈急促的光影表现，隐喻了闪光灯和观察者的存在，压平的四方造型拉近且打乱了主体和客体／观察者和被观察者的场域分配，毫无景深的视觉提示则赋予房间内的主动观察者更高阶的审判者的地位，但艺术家刻意营造的匿名性却又将这一连串的审判过程私密化，徒留给被动观察者一连串的疑问，以及成为局外人的被抛弃感。

Firstly, there are less secure and efficient threshold schemes; secondly, the research on multi-secret sharing is rather weak; thirdly, usual verifiable secret sharing don't consider the partners' anonymity, while it is just people's expectation. Last but not least, the problem of variety on shares is becoming a more obvious restrict of efficiency, especially in the facets of the lost and being districted of shares. On the application of verifiable secret sharing, there are also two inadequates : on the one hand , verifiable secret sharing has been used in much threshold cryptography but in less verifiable signatures.

然而，经过认真总结、分析该领域目前研究的发展状况（具体结果将在第一章给出），我们发现在可验证秘密分享的研究方面，仍有下列四个不足之处：一是现有的安全、高效的门限方案不多；二是对多秘密分享的研究非常薄弱，在已有的文献中还见不到安全、实用的可验证多秘密分享方案；三是通常的秘密分享方案没有考虑秘密分享者的匿名性，而这恰恰是人们所希望的；四是秘密分享者的动态管理问题已经越来越明显的制约现有方案的安全，尤其是密钥份额丢失或被破坏时如何恢复更是没有被深入探讨。

Internet provides unprecedented convenience and freedom for people. Network media broaden range and depth of transmission and break limit of information transmission form. People transfer their role freely for mutual-action of network, audiences initiatively offer information instead of accepting them passively. Freedom accompanying new technology impacts greatly social fixed law and moral criterion leading to weakening social control. Network consensus---traditional consensus with new carrier, personalizing and systematizing network forum、personal website、blog、wiki become abreaction location of information poor and marginals because of anonymity and mutual-action of Internet and randomness of personal speech.

互联网为人类提供了前所未有的便利与自由，网络媒体拓宽了传播的广度和深度，打破了信息传播形式的界限，网络的互动性使人们自由转换角色，受众不再被动接受信息，而是主动提供传播信息，高技术带来的&自由&对社会既定的法律法规、道德规范带来了极大冲击，导致社会控制弱化，而网络舆论，使传统舆论有了新的载体，互联网的匿名性、互动性，个人发言的随意性和无限性，个人化、组织化的网络论坛、个人网站、blog、wiki成为信息穷人和边缘人群发泄的场所。

In this paper, the verifiability of the voters' qualification and talliers' identification will be solved by a dynamic multi-secret sharing scheme without invoking more zero knowledge proof to maintain privacy, universal verifiablitlity, and anonymity of ballots.

提供的电子投票方案，无须调用多次交互式的零知识证明验证投票人的选举资格和监票人的身份，而是利用动态多密门体制方便地实现了选票的秘密性、广泛可验证性、公平性和匿名性，较之以前的投票方案具有较高的通信效率和安全性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
