زبان: انگلیسی

 

توضیحات درباره کتاب:

Cryptography has crept into everything, from Web browsers and e-mail programs to cell phones, bank cards, cars and even into medical implants. In the near future we will see many new exciting applications for cryptography such as radio frequency identification (RFID) tags for anti-counterfeiting or car-to-car communications (we’ve worked on securing both of these applications). This is quite a change from the past, where cryptography had been traditionally confined to very specific applications, especially government communications and banking systems.

As a consequence of the pervasiveness of crypto algorithms, an increasing number of people must understand how they work and how they can be applied in practice. This book addresses this issue by providing a comprehensive introduction to
modern applied cryptography that is equally suited for students and practitioners in industry.
Our book provides the reader with a deep understanding of how modern cryptographic schemes work. We introduce the necessary mathematical concepts in a way that is accessible for every reader with a minimum background in college-level
calculus. It is thus equally well suited as a textbook for undergraduate or beginning graduate classes, or as a reference book for practicing engineers and computer scientists who are interested in a solid understanding of modern cryptography.
The book has many features that make it a unique source for practitioners and students. We focused on practical relevance by introducing most crypto algorithms that are used in modern real-world applications. For every crypto scheme, up-to-date security estimations and key length recommendations are given. We also discuss the important issue of software and hardware implementation for every algorithm. In addition to crypto algorithms, we introduce topics such as important cryptographic  protocols, modes of operation, security services and key establishment techniques.
Many very timely topics, e.g., lightweight ciphers which are optimized for constrained applications (such as RFID tags or smart cards) or new modes of operations, are also contained in the book.

A discussion section at the end of each chapter with annotated references provides plenty of material for further reading. For classroom use, these sections are an excellent source for course projects. In particular, when used as a textbook, the
companion website for the book is highly recommended:

Abstract

Children and adults experience pervasive difficulties understanding symbolic fractions. These difficulties have led some to propose that components of the human neurocognitive architecture, especially systems like the approximate number system (ANS), are ill-suited for learning fraction concepts. However, recent research in developmental psychology and neuroscience has revealed neurocognitive architectures—a “ratio processing system” (RPS)—tuned to the holistic magnitudes of nonsymbolic ratios that may be ideally suited for grounding fraction learning. We review this evidence alongside our own recent behavioral and brain imaging work demonstrating that nonsymbolic ratio perception is related to understanding fractions. We argue that this nonsymbolic RPS supports symbolic fraction understanding, similar to how the ANS supports whole-number understanding. We then outline a number of open questions about the RPS and the ways in which it may be used to support fractions learning.
