Introduction to Modern Cryptography

This updated and expanded second edition of a highly praised text provides a rigorous yet accessible account of modern cryptography, focusing on formal definitions, assumptions, and rigorous proofs of security. The first half of the book gives an extensive treatment of private-key cryptography, including encryption, message authentication, and design principles for block ciphers. The second half focuses on public-key cryptography, including number theory; the RSA, Diffie-Hellman, and El Gamal cryptosystems; public-key encryption and digital signatures; and the random oracle model and its applications.
