Introduction to Modern Cryptography: Third Edition (Chapman & Hall/CRC Cryptography and Network Security Series)

A rigorous, introductory treatment of modern cryptography, focusing on definitions, precise assumptions, and proofs of security as distinguishing features from classical cryptography. It explores private-key encryption in depth, covering concepts like chosen-plaintext attacks (CPA-security) and chosen-ciphertext attacks (CCA-security), along with practical modes of operation like CBC and CTR. The text then transitions to message authentication codes (MACs), emphasizing message integrity against active adversaries and constructing secure MACs using pseudorandom functions and hash functions. Finally, the source expands into public-key cryptography, discussing key exchange, digital signatures, and public-key encryption schemes like RSA and El Gamal, all while grounding these concepts...
