Introduction to Modern Cryptography

Introduction to Modern Cryptography is the most relied-upon source in the field. The book provides a mathematically rigorous yet accessible treatment of this fascinating subject. This is an updated edition of the most widely used introduction to cryptography textbook. The authors have kept this book as up-to-date and with the feedback from instructors and students alike, the presentation is refined, current, and accurate.

The bookÂ’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 this book is that it presents theoretical foundations with an eye toward understanding the latest cryptographic standards in wide use today. This revised edition includes all the updates made to the third edition, including:

· 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 covering 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 “post-quantum” encryption and signature schemes.

Cryptography is now a part of our everyday lives. Whether ensuring the privacy of data sent over the Internet, making password cracking more difficult, or providing integrity for digitally signed documents cryptography is involved in many daily tasks.

Containing worked examples and updated exercises, Introduction to Modern Cryptography 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.
