"Whether ensuring the privacy of data sent over the Internet, making password cracking more difficult, or providing integrity for digitally signed documents, cryptography is now part of our everyday lives. Following two previous editions that have led it to become the most relied-upon source in the field, Introduction to Modern Cryptography provides mathematically rigorous yet accessible treatment of this subject. This book's focus is on modern 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. Containing worked examples and updated exercises, Introduction to Modern Cryptography can serve as a textbook for undergraduate or graduate-level course in cryptography, a reference for graduate students, researchers, and practitioners, or a general introduction suitable for self-study."--Adapted from back cover.
