可实施的

Finally the implement and consignation of running prove the feasibility of various above-mentioned theories and technical can carry out.

最终系统的实施和交付运行证实了上述各种理论与技术的可实施性。

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。

Firstly, proem, it concise introduces the background ; Secondly, it introduces the reform of the commission system and the dilemma of the securities companies in our country; Thirdly, it puts forward the idea of implementation of "Optionally differential strategies " as the natural choice for the future development of the securities brokers in our country , through the analysis of the current competitive environment of the securities companies in our country and study on the alternatives of competitive strategies ; The forth , it describes how to practice " Optionally differential strategies",which including three aspect: the choice of the core competition ability, the measures for the implementation are brought forth ,and the condition of practice the strategies; The fifth, it s the summary of the dissertation.

第一部分，简介论文写作背景；每二部分，介绍我国佣金制度改革以及改革后我国证券公司所面临的困境；第三部分，通过对现阶段我国证券公司竞争环境的分析，进行竞争战略选择研究，提出实施选择性差别化战略应成为我国证券商未来发展的必然选择。第四部分，提出"选择性差别化战略"的实施措施，包括拓展业务领域、拓宽交易渠道及改革证券商管理模式三方面可操作的内容；第五部分，对全文作概括性的总结。

You can also use cloaked Wraiths to scout the enemy if they do not have detection yet.

敌方若尚未建造反隐形建筑，人族同样可以用隐身的隐飞（Wraith，人族一种空中作战单位，可实施对地对空攻击，升级后可以隐身，习惯上叫隐飞，译者注）实施侦察。

The split between the two groups can hardly be papered over.
