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。

但在投资50亿美元的离地装置，以及未能预料到全球无线网域产品的威胁，即便摩托罗拉过去曾短暂支持铱卫星，铱卫星还是在1999年宣告破产。

Difference target leads to difference decision element. The decision element of the state include ecology and poverty, the decision element of region government include achievement, system or policy, and money, the decision element for migrator include personality, distance, infrastructure, culture and migratory cost.

不同的目标导致决策因素的不同，认为生态和缓贫是国家生态移民决策的主要因素；认为政绩、制度、资金因素是地方政府决策的主要因素；个体、迁移距离、迁入地基础设施、社区文化、迁移者的成本效益是影响迁移者决策的主要因素，并以此构建国家、地方政府和迁移个人的决策模型。

It consider that region government should follow the principles including ecological sustainable development, land supply effective, perfect basic infrastructure and social service system, which is the countermeasure for selecting place to migration. To do well plan, construction and community introjecting is the scientific construction for the place of migration. To make the implement procedure criterion, to guarantee the money supply, to pay attention to migrator work and life is the countermeasures to optimize region government action for ecological migration.

认为遵循生态持续发展、土地有效供给、基础设施建设和社会化服务体系完善、城镇区域辐射等原则是科学选择生态移民迁入地的基本对策；做好迁入地规划、建设和社区整合是科学建设迁入地的对策；科学组织实施、保障资金、关注移民人口生产生活是优化地方政府生态移民行为的主要对策。
