Understanding Cryptography

Author: Christof Paar
Publisher: Springer Science & Business Media
ISBN: 3642041019
Category : Computers
Languages : en
Pages : 382

Book 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 book’s 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.

Hieroglyphs: A Very Short Introduction

Author: Penelope Wilson
Publisher: Oxford University Press, USA
ISBN: 0192805029
Category : Art
Languages : en
Pages : 144

Book Description
Hieroglyphs were far more than a language. They were an omnipresent and all-powerful force in communicating the messages of ancient Egyptian culture for over three thousand years. In this exciting new study, Penelope Wilson explores the cultural significance of hieroglyphs with an emphasis on previously neglected areas such as cryptography and the continuing deciphering of the script in modern times.

Number Theory

Author: Robin Wilson
Publisher: Oxford University Press, USA
ISBN: 0198798091
Category : Mathematics
Languages : en
Pages : 177

Book Description
Number theory is the branch of mathematics primarily concerned with the counting numbers, especially primes. It dates back to the ancient Greeks, but today it has great practical importance in cryptography, from credit card security to national defence. This book introduces the main areas of number theory, and some of its most interesting problems.

Computer Science

Author: Subrata Dasgupta
Publisher: Oxford University Press
ISBN: 0198733461
Category : Computers
Languages : en
Pages : 169

Book Description
While the development of Information Technology has been obvious to all, the underpinning computer science has been less apparent. Subrata Dasgupta provides a thought-provoking introduction to the field and its core principles, considering computer science as a science of symbol processing.

Mathematics: A Very Short Introduction

Author: Timothy Gowers
Publisher: Oxford Paperbacks
ISBN: 9780192853615
Category : Mathematics
Languages : en
Pages : 172

Book Description
The aim of this volume is to explain the differences between research-level mathematics and the maths taught at school. Most differences are philosophical and the first few chapters are about general aspects of mathematical thought.
