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.

《现代密码学:原理与协议》内容简介：密码学在确保数据的私密性和完整性，以及计算机网络的安全性方面扮演了关键角色。乔纳森·卡茨和耶胡达·林德尔所著的《现代密码学：原理与协议》一书提供了对现代密码学严格而又容易理解的介绍，关注形式化的定义、精确的假设以及严格的证明。《现代密码学：原理与协议》介绍了现代密码学的核心原则，包括现代的、基于计算复杂性的安全，以克服完美安全的局限性。对对称密钥加密和消息鉴别也做了较大篇幅的介绍。同时，举例说明了分组密码，如DES和AES的设计原则，并且在低级原语层面展示了分组密码的可证明安全构造方法。《现代密码学：原理与协议》下半部分介绍公钥密码学。首先对数论知识进行了介绍，这些知识是理解RSA、Diffie-Hellman、El Gamal以及其他密码学系统所需要的。在探讨了公钥加密和数字签名之后，介绍了随机预言模型及其应用。无论作为教材、参考书或者自学用书，《现代密码学:原理与协议》呈献给读者透彻理解现代密码学这一迷人主题所需要的工具。

Introduction to Modern Cryptography, the most relied-upon textbook in the field, provides a mathematically rigorous yet accessible treatment of this fascinating subject. The authors have kept the book up-to-date while incorporating feedback from instructors and students alike; the presentation is refined, current, and accurate.

The book’s focus is on modern cryptography, which is distinguished from classical cryptography by its emphasis on definitions, precise assumptions, and rigorous proofs of security. A unique feature of the text is that it presents theoretical foundations with an eye toward understanding cryptography as used in the real world. This revised edition fixed typos and includes all the updates made to the third edition,

Enhanced treatment of several modern aspects of private-key cryptography, including authenticated encryption and nonce-based encryption. Coverage of widely used standards such as GMAC, Poly1305, GCM, CCM, and ChaCha20-Poly1305. New sections on the ChaCha20 stream cipher, sponge-based hash functions, and SHA-3. Increased coverage of elliptic-curve cryptography, including a discussion of various curves used in practice. A new chapter describing the impact of quantum computers on cryptography and providing examples of quantum-secure encryption and signature schemes. Containing worked examples and updated exercises, Introduction to Modern Cryptography, Revised Third Edition can serve as a textbook for undergraduate- or graduate-level courses in cryptography, a reference for graduate students, researchers, and practitioners, or a general introduction suitable for self-study.
