The security of PKI system itself is especially emphasized during the system design and implementation process, which is in accordance with the pervasive characteristic of PKI. Second, the concept of a Trusted Key Management Center is introduced for the first time. This technology greatly strengthens key management practices and allows for smooth transition from PKI to Key Management Infrastructure . Third, certificate status mechanisms are investigated in depth, and a certificate revocation performance simulation system is devised. All these work will provide guides to practice and employment of PKI applications. Based on time constraints, a new taxonomy for authenticated dictionaries is proposed. Fourth, formal analysis of OCSP protocol is carried out; then an efficient and scalable OCSP system is developed. Fifth, the special requirements caused by the working environments of Wireless PKI are analyzed. Based on communicative hashing and dynamic Merkle hash tree, an efficient certificate status validation method suitable for WPKI is presented. Sixth, one important kind of fair exchange protocols is studied, and a new CEMBS based on RSA cryptosystem is proposed. Afterwards, a novel fair exchange protocol totally based on RSA signature scheme is devised.

在系统设计和实现的过程中，考虑到PKI作为普适性安全基础平台的特点，特别强调PKI系统自身的安全性；第二，首次在PKI系统的设计中提出了"可信密钥管理中心"的概念，这一独特设计大大地强化了密钥管理功能的实施，为PKI向密钥管理基础设施的平滑过渡提供了良好的技术准备；第三，对证书状态验证机制进行了深入研究，设计了证书状态模拟系统，以指导PKI系统和应用的部署和实施；在此基础上，基于时间约束首次给出了认证字典的一种新的分类方法；第四，对OCSP协议进行了形式化分析，设计和实现了一种高效、可扩展的OCSP系统；第五，分析了WPKI工作环境对设计安全基础平台提出的特殊要求，结合无线移动设备的具体特点，基于可交换杂凑函数和动态Merkle杂凑树设计出了一种适用于WPKI环境的高效证书状态查询机制；第六，对一类公平交换协议进行了深入的研究，从设计公平交换协议的密码基础结构出发，提出了一种新型的基于RSA密码体制的高效CEMBS；在此工作的基础上，设计了一种基于RSA密码体制的最优化公平交换协议。

之后对平台开发中使用的类进行定义说明，明确和规范了类之间的调用与功能，进而实现了该平台。

Am June 2 at the Taipei Computer Show at the conference, Tt go DesignworksUSA in addition to outside executives, AMD vice president of business development platform Levi Murry will also be attending, I believe that since Level 10 chassis will become the Queen's AMD platform products .

6月2日上午在台北电脑展举行的发布会上，Tt除了请到DesignworksUSA高管外，AMD平台业务开发副总裁Levi Murry也将到场，相信此后Level 10机箱将成为AMD产品的御用展示平台。

From an integrated perspective, three companies have their own features in marketing process. ChinaHR adopts the Narrowcast practice; 51job integrates the media resources in various local areas and builds up the mode of interaction by combining websites with newspapers; Zhaopin Ltd perfectly avails itself of the successful media platforms. All of them have yielded a lot. Therefore, it is reasonable to conclude that both mass media and narrowcast can play their roles and the key is to spread the information to the target customers in the real sense and thus to upgrade the reputation and brand influence.

综合分析来看，三个公司的市场推广各具特色，中华英才网采用的是针对直接目标群体的小众传播，前程无忧利用的是整合各地传媒资源，搭建平台并采用网站+报纸的互动推广模式，智联招聘则借助强势的媒体平台，三个网站都取得了较好的效果，由此可见，大众传播和小众传播对于招聘网站都能起到作用，关键在于是不是有效的传达给了目标消费者，并借此能够提升网站的知名度和品牌。
