Anonymity and unobservability have become key issues in the context of securing privacy on the Internet and in other communication networks. Services that provide anonymous and unobservable access to the Internet are important for electronic commerce applications as well as for services where users want to remain anonymous.This book is devoted to the design and realization of anonymity services for the Internet and other communcation networks. The book offers topical sections on： attacks on systems， anonymous publishing， mix systems， identity management， pseudonyms and remailers. Besides nine technical papers， an introduction clarifying the terminology for this emerging area is presented as well as a survey article introducing the topic to a broader audience interested in security issues.

随着Internet的兴起，企业网络安全越来越受到重视，尤其是电子商务的大力推动，使得电子交易安全的话题，成为人们讨论的焦点。微软主推的Microsoft．NET平台中包含了企业网络安全这一项，其主要的产品有Internet Security and Acceleration Server简称ISA Server，它集成了Proxy Server、Firewall、访问控制、高速缓存、安全认证、数据包过滤、NAT、流量控制及VPN等多种功能，足以应付一般企业所需的网络安全。Microsoft ISA Server 2000是目前唯一在Windows 2000Server平台上，同时具有防火墙与网站缓存的服务器软件。其设计是针对当今使用Internet的企业安全需求，提供多层次的企业级防火墙，并结合Microsoft ISA Server 2000专用的防毒软件，在企业Internet推出的第一道关卡，保护网络资源，以避免病毒、黑客及未获授权的访问行为。并同时具有加速公司内部对内与对外的访问速度，节省Internet网络带宽，提供用户更快的Web访问速度。本书由台湾松岗电脑图书资料股份有限公司提供版权，经中国铁道出版社计算机图书项目中心审选。李自运、梁秀玲、关超、史广顺、张瀚文、陈辑超、马超、杨小平、杨小军、段小明、杨军、裘伟力、陈贤淑及孟丽花等同志参与了本书的整稿及编排工作。中国铁道出版社2001年11月

This book constitutes the thoroughly refereed post-proceedings of the 7th International Workshop on Fast Software Encryption， FSE 2000， held in New York City， USA in April 2000.The 21 revised full papers presented were carefully reviewed and selected from a total of 53 submissions. The volume presents topical sections on stream-cipher cryptanalysis， new ciphers， AES cryptanalysis， block-cipher cryptanalysis， and theoretical work.

Invasion of privacy and misuse of personal data are among the most obvious negative effects of today's information and communication technologies. Besides technical issues from a variety of fields， privacy legislation， depending on national activities and often lacking behind technical progress， plays an important role in designing， implementing， and using privacy-enhancing systems.Taking into account technical aspects from IT security， this book presents in detail a formal task-based privacy model which can be used to technically enforce legal privacy requirements. Furthermore， the author specifies how the privacy model policy has been implemented together with other security policies in accordance with the Generalized Framework for Access Control （GFAC）.This book will appeal equally to R&D professionals and practitioners active in IT security and privacy， advanced students， and IT managers.
