《信息安全基础》介绍信息安全事先防护理论和技术的基础知识，不追求大而全，而把目标确定为使学生学到结构化的知识和对信息安全有一个系统的了解。《信息安全基础》由基本概念、基本算法、基础密码协议、安全模型、应用技术和基础设施共六章组成。前四章为《普通高等学校信息与计算科学专业系列丛书：信息安全基础》的重点，内容包括基本概念、基本算法与模型的详细讨论。第五章对繁杂的实用技术进行了介绍，主要包括Web安全、数据库安全、电子交易安全三个重要的应用技术的介绍，而对操作系统安全、数据库安全、病毒防护、防火墙、VPN及入侵检测等系统安全方面的知识仅做了概念性的介绍。第六章围绕密钥安全和授权体系对PKI、SKI、PMI的基本知识进行讲述。《信息安全基础》适用于数学、计算机、通信、电子和信息专业的本科高年级学生和研究生一学期课程使用。

本书讲述如何让Skype（一个正在像风暴一样席卷全球的Internet电话应用程序）为你工作。拥有超过5000万注册用户以及任何时候在线人数都超过300万，Skype是继Web以来最大的Internet现象之一。越来越多的用户切断他们连接到原来电话公司的线路，代之以通过全部或局部更换到使用Skype而节省了一大笔钱。但是，本书不仅仅是省钱那么简单。Skype给世界带来了一个全新的东西能够做旧式电话系统不能做的事情。呼叫伴随你的左右，不论家庭电话号码还是移动电话号码，只要登录到Skype，呼叫就会找到你。甚至还可以把到电话的链接放到网页上。本书说明了如何：l最大化结余l建立一个Skype服务器l把Skype整合到网页中l把Skype的快捷方式放大桌面上l编写脚本来自动化Skypel管理安全设置l避免Skype上的推销员l使用聊天、文件传输、会议和视频l解决性能跟质量的问题l找到911和411服务的替代品l用Skype替代家庭电话系统l在Windows、Linux、Mac OS X以及Pocket PC上使用Skype不管你是Skype新手还是想研究Skype内部的高手，本书都非常适合你。

This book constitutes the refereed proceedings of the Third International Workshop on Fault Diagnosis and Tolerance in Cryptography， FDTC 2006， held in Yokohama， Japan in October 2006.The 12 revised papers of FDTC 2006 are presented together with 9 papers from FDTC 2004 and FDTC 2005 that passed a second round of reviewing.
