Cryptography is ubiquitous and plays a key role in ensuring data secrecy and integrity as well as in securing computer systems more broadly. Introduction to Modern Cryptography provides a rigorous yet accessible treatment of this fascinating subject.
The authors introduce the core principles of modern cryptography, with an emphasis on formal definitions, clear assumptions, and rigorous proofs of security. The book begins by focusing on private-key cryptography, including an extensive treatment of private-key encryption, message authentication codes, and hash functions. The authors also present design principles for widely used stream ciphers and block ciphers including RC4, DES, and AES, plus provide provable constructions of stream ciphers and block ciphers from lower-level primitives. The second half of the book covers public-key cryptography, beginning with a self-contained introduction to the number theory needed to understand the RSA, Diffie-Hellman, and El Gamal cryptosystems (and others), followed by a thorough treatment of several standardized public-key encryption and digital signature schemes.
Integrating a more practical perspective without sacrificing rigor, this widely anticipated Second Edition offers improved treatment of:
Containing updated exercises and worked examples, Introduction to Modern Cryptography, Second Edition can serve as a textbook for undergraduate- or graduate-level courses in cryptography, a valuable reference for researchers and practitioners, or a general introduction suitable for self-study.
Jonathan Katz is a professor of computer science at the University of Maryland, and director of the Maryland Cybersecurity Center. He has published over 100 articles on cryptography, and serves as an editor of the Journal of Cryptology, the premier journal of the field. Prof. Katz has been invited to give introductory lectures on cryptography for audiences in academia, industry, and government, as well as an on-line cryptography course through Coursera.
Yehuda Lindell is a professor of computer science at Bar-Ilan University. He has published more than 90 articles on cryptography and four books, and has considerable industry experience in deploying cryptographic schemes. Professor Lindell lectures widely in both academic and industry venues on both theoretical and applied cryptography, and has been recognized with two prestigious grants from the European Research Council.
