This book is a comprehensive, rigorous introduction to what the authors name 'modern' cryptography ... a novel approach to how cryptography is taught, replacing the older, construction-based approach. ... The concepts are clearly stated, both in an intuitive fashion and formally. ... I would heartily recommend this book to anyone who is interested in cryptography. ... the exercises are challenging and interesting, and can benefit readers of all academic levels. ... -IACR book reviews, January 2010 Over the past 30 years, cryptography has been transformed from a mysterious art into a mathematically rigorous science. The textbook by Jonathan Katz and Yehuda Lindell finally makes this modern approach to cryptography accessible to a broad audience. Readers of this text will learn how to think precisely about the security of protocols against arbitrary attacks, a skill that will remain relevant and useful regardless of how technology and cryptography standards change. The book uses just enough formalism to maintain precision and rigor without obscuring the development of ideas. It manages to convey both the theory's conceptual beauty and its relevance to practice. I plan to use it every time I teach an undergraduate course in cryptography. -Salil Vadhan, Harvard University, Cambridge, Massachusetts, USA ... the greatest attribute is the fact that the material is presented in such a unified way. These are not just a collection of topics from cryptography, thrown together at random. One topic leads effortlessly to the next. As such, this is a virtually indispensible resource for modern cryptography. -Donald L. Vestal, South Dakota State University, MAA Online, July 2008 ... gives an excellent introduction to the theoretical background of cryptography. It would be a fine textbook for an advanced undergraduate (or graduate) course in theoretical computer science for students who have already seen the rudiments of cryptography. It will be a valuable reference for researchers in the field ... -Steven D. Galbraith, Mathematical Reviews, 2009b The book is highly recommended as a textbook in cryptography courses at graduate or advanced undergraduate levels ... covers in a splendid way the main notions of current cryptography from the point of view of information-theoretical security. This corresponds indeed to a modern cryptography approach. -Guillermo Morales-Luna, Zentralblatt MATH, Vol. 1143
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.
