description: Cryptography is now ubiquitous  moving beyond the traditional environments such as government communications and banking systems we see cryptographic techniques realized in Web browsers e-mail programs cell phones manufacturing systems embedded software smart buildings cars and even medical implants. Today's designers need a comprehensive understanding of applied cryptography. After an introduction to cryptography and data security the authors explain the main techniques in modern cryptography with chapters addressing stream ciphers the Data Encryption Standard (DES) and 3DES the Advanced Encryption Standard (AES) block ciphers the RSA cryptosystem public-key cryptosystems based on the discrete logarithm problem elliptic-curve cryptography (ECC) digital signatures hash functions Message Authentication Codes (MACs) and methods for key establishment including certificates and public-key infrastructure (PKI). Throughout the book the authors focus on communicating the essentials and keeping the mathematics to a minimum and they move quickly from explaining the foundations to describing practical implementations including recent topics such as lightweight ciphers for RFIDs and mobile devices and current key-length recommendations. The authors have considerable experience teaching applied cryptography to engineering and computer science students and to professionals and they make extensive use of examples problems and chapter reviews while the books website offers slides projects and links to further resources. This is a suitable textbook for graduate and advanced undergraduate courses and also for self-study by engineers.
