自从人类开始会用笔书写，他们就开始用密码通讯了。密码并不仅仅与电报、军事或爱情相关，它已进入人类生活的很多层面：信用卡、保险柜、电脑等等。密码无处不在，同时又随时可能被破译。围绕密码所展开的斗争甚至远胜于战争本身，它既是人类智力的另类较量，又是数学的神秘之美的比拼。在《密码故事》中，作者西蒙·辛格讲述了关于间谍、阴谋和聪明才智的精彩故事，揭示了密码学引人入胜的历史。

THE LEGACY...First introduced in 1995, Cryptography: Theory and Practice garnered enormous praise and popularity, and soon became the standard textbook for cryptography courses around the world. The second edition was equally embraced, and enjoys status as a perennial bestseller. Now in its third edition, this authoritative text continues to provide a solid foundation for future breakthroughs in cryptography. WHY A THIRD EDITION? The art and science of cryptography has been evolving for thousands of years. Now, with unprecedented amounts of information circling the globe, we must be prepared to face new threats and employ new encryption schemes on an ongoing basis. This edition updates relevant chapters with the latest advances and includes seven additional chapters covering: Pseudorandom bit generation in cryptography Entity authentication, including schemes built from primitives and special purpose "zero-knowledge" schemes Key establishment including key distribution and protocols for key agreement, both with a greater emphasis on security models and proofs Public key infrastructure, including identity-based cryptography Secret sharing schemes Multicast security, including broadcast encryption and copyright protection THE RESULT...Providing mathematical background in a "just-in-time" fashion, informal descriptions of cryptosystems along with more precise pseudocode, and a host of numerical examples and exercises, Cryptography: Theory and Practice, Third Edition offers comprehensive, in-depth treatment of the methods and protocols that are vital to safeguarding the mind-boggling amount of information circulating around the world.

Cryptography plays a key role in ensuring the privacy and integrity of data and the security of computer networks. "Introduction to Modern Cryptography" provides a rigorous yet accessible treatment of modern cryptography, with a focus on formal definitions, precise assumptions, and rigorous proofs. The authors introduce the core principles of modern cryptography, including the modern, computational approach to security that overcomes the limitations of perfect secrecy. An extensive treatment of private-key encryption and message authentication follows. The authors also illustrate design principles for block ciphers, such as the Data Encryption Standard (DES) and the Advanced Encryption Standard (AES), and present provably secure constructions of block ciphers from lower-level primitives.The second half of this book focuses on public-key cryptography, beginning with a self-contained introduction to the number theory needed to understand the RSA, Diffie-Hellman, El Gamal, and other cryptosystems. After exploring public-key encryption and digital signatures, this book concludes with a discussion of the random oracle model and its applications. Serving as a textbook, a reference, or for self-study, "Introduction to Modern Cryptography" presents the necessary tools to fully understand this fascinating subject.

Security is the number one concern for businesses worldwide. The gold standard for attaining security is cryptography because it provides the most reliable tools for storing or transmitting digital information. Written by Niels Ferguson, lead cryptographer for Counterpane, Bruce Schneier's security company, and Bruce Schneier himself, this is the much anticipated follow-up book to Schneier's seminal encyclopedic reference, Applied Cryptography, Second Edition (0-471-11709-9), which has sold more than 150,000 copies. Niels Ferguson (Amsterdam, Netherlands) is a cryptographic engineer and consultant at Counterpane Internet Security. He has extensive experience in the creation and design of security algorithms, protocols, and multinational security infrastructures. Previously, Ferguson was a cryptographer for DigiCash and CWI. At CWI he developed the first generation of off-line payment protocols. He has published numerous scientific papers. Bruce Schneier (Minneapolis, MN) is Founder and Chief Technical Officer at Counterpane Internet Security, a managed-security monitoring company. He is also the author of Secrets and Lies: Digital Security in a Networked World (0-471-25311-1).

很多密码方案与协议，特别是基于公钥密码体制的，有一些基础性或所谓的“教科书式密码”版本，这些版本往往是很多密码学教材所包含的内容。本书采用了一种不同的方式来介绍密码学——更加注重适于应用的密码学方面。它解释了那些“教科书式密码”版本仅适合于理想世界的原因，即数据是随机的、坏人的表现不会超越预先的假定。本书通过展示“教科书式密码”版本的方案、协议、和系统在各种现实应用场合存在着很多攻击，来揭示“教科书式密码”版本在现实生活中的不适用性。本书有选择性的介绍了一些实用的密码方案、协议和系统，其中多数已成为了标准或事实上的标准，对其进行了详细的研究，解释了其工作原理，讨论了其实际应用，并且常会以建立安全性形式证明的方式来考察它们的强（实用）安全性。另外，本书还完整地给出了学习现代密码学所必备的理论基础知识。 本书可作为高学院校计算机专业研究生或高年级本科生的教材，也可供密码安全架构师、工程人员、开发人员以及管理人员参考。
