第二十一世纪是知识的时代
21世纪是知识经济的时代，组织和利用知识信息的有力武器――数据库将继续得到广泛应用。数据库(Database，即DB)是存储在一起的相关数据的集合，是存储数据的“仓库”。其名词源于20世纪50年代，美国为战争的需要，把各种情报案中在一起，存入计算机。60年代数据库帮助设计了阿波罗登月火箭，推动了数据库技术的产生。70年代，数据库蓬勃发展，网状系统和层次系统占领了市场，并且关系数据库理论也日趋完善。80年代起，关系数据库产品已相当成熟，后来有了分布式数据库系统(Distributed Database Systems)、数据库机(Datsbase Machines)、知识库(Knowledge Base)系统相知识机。现在，数据库技术已成为计算机领域最重要的技术之一，它是软件学科中一个独立分支(即研究数据库的结构、存储、设计和使用的一门软件学科)。-The 21st century is the era of knowledge-based economy, organization and use of knowledge and information of a powerful weapon- the database will continue to be widely applied. Database (Database, or DB) is stored together a collection of related data is stored data "warehouse." The term originated from the 20th century, 50 s, the United States for the war needs, the case of the various information together into a computer. 60 s database to help design the Apollo moon rocket to promote the generation of database technology. 70 years, vigorous development of the database, network systems, and levels of the system o

C++, although a marvelous language, isn t perfect. Matthew Wilson has been working with it for over a decade, and during that time he has found inherent limitations that require skillful workarounds. In this book, he doesn t just tell you what s wrong with C++, but offers practical techniques and tools for writing code that s more robust, flexible, efficient, and maintainable. He shows you how to tame C++ s complexity, cut through its vast array of paradigms, take back control over your code--and get far better results

使用威尔配对,本文提出了一种基于身份的环签密方案,给出了具体的算法.该方案能够使消息的
发送者以一种完全匿名的方式发送消息,并且同时实现保密性和认证性两种功能.我们证明了在决策双线性Diffie-
Hellman问题难解的假设下,新提出的方案对自适应选择密文攻击是安全的.与传统的先签名后加密的方案
相比,本方案中密文长度有了明显的降低,在低带宽的要求下更加可行.-Will the use of matching, this paper, a ring of identity-based signcryption program, given a specific algorithm. The program will enable the sender information in a completely anonymous way to send messages, and at the same time to achieve confidentiality and authentication of two functions. We prove that in the decision-making bilinear Diffie-Hellman problem difficult to resolve under the assumption that the new proposal for adaptive chosen ciphertext attack is safe. with the traditional first signed encrypted program compared ciphertext of the program significantly reduced the length, in the low-bandwidth request more feasible.
