Introduction to Cryptography: Principles and Applications (Information Security and Cryptography)by Hans Delfs
Synopses & Reviews
Due to the rapid growth of digital communication and electronic data exchange, information security has become a crucial issue in industry, business, and administration. Modern cryptography provides essential techniques for securing information and protecting data. In the first part, this book covers the key concepts of cryptography on an undergraduate level, from encryption and digital signatures to cryptographic protocols. Essential techniques are demonstrated in protocols for key exchange, user identification, electronic elections and digital cash. In the second part, more advanced topics are addressed, such as the bit security of one-way functions and computationally perfect pseudorandom bit generators. The security of cryptographic schemes is a central topic. Typical examples of provably secure encryption and signature schemes and their security proofs are given. Though particular attention is given to the mathematical foundations, no special background in mathematics is presumed. The necessary algebra, number theory and probability theory are included in the appendix. Each chapter closes with a collection of exercises. The second edition contains corrections, revisions and new material, including a complete description of the AES, an extended section on cryptographic hash functions, a new section on random oracle proofs, and a new section on public-key encryption schemes that are provably secure against adaptively-chosen-ciphertext attacks.
Modern cryptography provides essential techniques for securing information and protecting data. This book provides an introduction to the key concepts of cryptography, from encryption and digital signatures to cryptographic protocols, such as electronic elections and digital cash. It applies probability theory to make basic notions precise, such as the security of cryptographic schemes. More advanced topics are also addressed, such as the bit security of one-way functions and computationally perfect pseudo-random generators. No special background in mathematics is needed to understand the material; an explanation of the necessary mathematics is given in two appendices. In addition, to make the material readily accessible, the authors use the same examples throughout the book and provide complete proofs.
It will be an ideal textbook for an undergraduate course in cryptography as well as a guide to those wanting an introduction to the subject.
