Serious Cryptography is the much anticipated review of modern cryptography by cryptographer JP Aumasson. This is a book for readers who want to understand how cryptography works in today´s world. The book is suitable for a wide audience, yet is filled with mathematical concepts and meaty discussions of how the various cryptographic mechanisms work. Chapters cover the notion of secure encryption, randomness, block ciphers and ciphers, hash functions and message authentication codes, public-key crypto including RSA, Diffie-Hellman, and elliptic curves, as well as TLS and post-quantum cryptography. Numerous code examples and real use cases throughout will help practitioners to understand the core concepts behind modern cryptography, as well as how to choose the best algorithm or protocol and ask the right questions of vendors. Aumasson discusses core concepts like computational security and forward secrecy, as well as strengths and limitations of cryptographic functionalities related to
The purpose of this book is to introduce the reader to arithmetic topics, both ancient and modern, which have been at the center of interest in applications of number theory, particularly in cryptography. No background in algebra or number theory is assumed, and the book begins with a discussion of the basic number theory which is needed. The approach taken is algorithmic, emphasizing estimates of the efficiency of the techniques which arise from the theory. A special feature is the inclusion of recent application of the theory of elliptic curves. Extensive imaginative exercises and careful, revealing answers have been included in all of the chapters. The information society and the computer age have given rise to innumerable applications for cryptography besides the original motivation of secure communication. Thus, cryptography is a relatively fast-moving field. The new edition contains due to that fact substantial revisions and updated references.
A valuable reference for the novice as well as for the expert who needs a wider scope of coverage within the area of cryptography, this book provides easy and rapid access of information and includes more than 200 algorithms and protocols; more than 200 tables and figures; more than 1,000 numbered definitions, facts, examples, notes, and remarks; and over 1,250 significant references, including brief comments on each paper. Cryptography, in particular public-key cryptography, has emerged an important discipline that is not only the subject of an enormous amount of research, but provides the foundation for information security in many applications. This title provides a treatment that introduces the practical aspects of both conventional and public-key cryptography.
Develop a greater intuition for the proper use of cryptography. This book teaches the basics of writing cryptographic algorithms in Python, demystifies cryptographic internals, and demonstrates common ways cryptography is used incorrectly. Cryptography is the lifeblood of the digital world´s security infrastructure. From governments around the world to the average consumer, most communications are protected in some form or another by cryptography. These days, even Google searches are encrypted. Despite its ubiquity, cryptography is easy to misconfigure, misuse, and misunderstand. Developers building cryptographic operations into their applications are not typically experts in the subject, and may not fully grasp the implication of different algorithms, modes, and other parameters. The concepts in this book are largely taught by example, including incorrect uses of cryptography and how ´´bad´´ cryptography can be broken. By digging into the guts of cryptography, you can experience what works, what doesn´t, and why. What You´ll Learn Understand where cryptography is used, why, and how it gets misused Know what secure hashing is used for and its basic properties Get up to speed on algorithms and modes for block ciphers such as AES, and see how bad configurations break Use message integrity and/or digital signatures to protect messages Utilize modern symmetric ciphers such as AES-GCM and CHACHA Practice the basics of public key cryptography, including ECDSA signatures Discover how RSA encryption can be broken if insecure padding is used Employ TLS connections for secure communications Find out how certificates work and modern improvements such as certificate pinning and certificate transparency (CT) logs Who This Book Is For IT administrators and software developers familiar with Python. Although readers may have some knowledge of cryptography, the book assumes that the reader is starting from scratch.
The Manga Guide to Cryptography breaks down how ciphers work, what makes them secure or insecure, and how to decode them. Comic illustrations make it easy to learn about classic substitution, polyalphabetic, and transposition ciphers; symmetric-key algorithms like block and DES (Data Encryption Standard) ciphers; how to use public key encryption technology to generate public/private keys and cryptograms; practical applications of encryption such as digital signatures, identity fraud countermeasures, and ´man in the middle´ attack countermeasures.
After two decades of research and development, elliptic curve cryptography now has widespread exposure and acceptance. Industry, banking, and government standards are in place to facilitate extensive deployment of this efficient public-key mechanism. Anchored by a comprehensive treatment of the practical aspects of elliptic curve cryptography (ECC), this guide explains the basic mathematics, describes state-of-the-art implementation methods, and presents standardized protocols for public-key encryption, digital signatures, and key establishment. In addition, the book addresses some issues that arise in software and hardware implementation, as well as side-channel attacks and countermeasures. Readers receive the theoretical fundamentals as an underpinning for a wealth of practical and accessible knowledge about efficient application. Features & Benefits: Breadth of coverage and unified, integrated approach to elliptic curve cryptosystems Describes important industry and government protocols, such as the FIPS 186-2 standard from the U.S. National Institute for Standards and Technology Provides full exposition on techniques for efficiently implementing finite-field and elliptic curve arithmetic Distills complex mathematics and algorithms for easy understanding Includes useful literature references, a list of algorithms, and appendices on sample parameters, ECC standards, and software tools This comprehensive, highly focused reference is a useful and indispensable resource for practitioners, professionals, or researchers in computer science, computer engineering, network design, and network data security.
As information is becoming a fundamental resource, adequate information protection is one of the crucial factors for the expected growth of information-based processes in industry, business, and administration. Cryptography is a key technology for achieving information security in communications, computer systems, electronic commerce, and, more generally, in the emerging information society. Given the strong interest in information protection, Springer has decided to launch Information Security and Cryptography (IS&C) as a prestigious hardbound book series covering all relevant topics, ranging from theory to advanced applications. The series will consist of textbooks, monographs, and coherent multi-author anthologies on hot topics. IS&C will complement Springers other crypto-related publishing activities. While the Journal of Cryptology and LNCS are devoted to the timely publication of high-quality research results, the new IS&C series will be dedicated to the top -quality, comprehensive treatment of topics that have reached a sufficient level of maturity.
There are many surprising connections between the theory of numbers, which is one of the oldest branches of mathematics, and computing and information theory. Number theory has important applications in computer organization and security, coding and cryptography, random number generation, hash functions, and graphics. Conversely, number theorists use computers in factoring large integers, determining primes, testing conjectures, and solving other problems. This book takes the reader from elementary number theory, via algorithmic number theory, to applied number theory in computer science. It introduces basic concepts, results, and methods, and discusses their applications in the design of hardware and software, cryptography, and security. It is aimed at undergraduates in computing and information technology, but will also be valuable to mathematics students interested in applications. In this 2nd edition full proofs of many theorems are added and some corrections are made.
This is a graduate textbook of advanced tutorials on the theory of cryptography and computational complexity. In particular, the chapters explain aspects of garbled circuits, public-key cryptography, pseudorandom functions, one-way functions, homomorphic encryption, the simulation proof technique, and the complexity of differential privacy. Most chapters progress methodically through motivations, foundations, definitions, major results, issues surrounding feasibility, surveys of recent developments, and suggestions for further study. This book honors Professor Oded Goldreich, a pioneering scientist, educator, and mentor. Oded was instrumental in laying down the foundations of cryptography, and he inspired the contributing authors, Benny Applebaum, Boaz Barak, Andrej Bogdanov, Iftach Haitner, Shai Halevi, Yehuda Lindell, Alon Rosen, and Salil Vadhan, themselves leading researchers on the theory of cryptography and computational complexity. The book is appropriate for graduate tutorials and seminars, and for self-study by experienced researchers, assuming prior knowledge of the theory of cryptography.
