Introduction to Cryptography, Second Edition

EBook Description: Continuing a bestselling tradition, An Introduction to Cryptography, Second Edition features all of the requisite background material on number theory and algorithmic complexity, includes a historical look at the field, and offers updated and expanded exercise sets. In addition to updates throughout the text, this edition includes two new chapters on current and future applications that cover topics such as electronic mail, Internet security, protocol layers and SSL, firewalls, client-server model and cookies, network security, wireless security, smart cards, and biometrics. The book also provides additional information on cryptanalysis and primality testing as well as appendices on DES and primitive roots. An undergraduate introductory course text, intended for readers with little or no background in number theory (the math is presented as needed). The text also contains enough advanced, optional material to challenge the more informed student. Mollin (mathematics, U. of Calgary) begins with the origins of cryptography and then covers symmetric-key cryptosystems, public-key cryptosystems, and primality testing. The final chapter deals with advanced topics: elliptic curves, zero-knowledge, and quantum cryptography.

Gain the skills and knowledge needed to create effective data security systems. This book updates readers with all the tools, techniques, and concepts needed to understand and implement data security systems. It presents a wide range of topics for a thorough understanding of the factors that affect the efficiency of secrecy, authentication, and digital signature schema. Most importantly, readers gain hands-on experience in cryptanalysis and learn how to create effective cryptographic systems.

The author contributed to the design and analysis of the Data Encryption Standard (DES), a widely used symmetric-key encryption algorithm. His recommendations are based on firsthand experience of what does and does not work.

Thorough in its coverage, the book starts with a discussion of the history of cryptography, including a description of the basic encryption systems and many of the cipher systems used in the twentieth century. The author then discusses the theory of symmetric- and public-key cryptography. Readers not only discover what cryptography can do to protect sensitive data, but also learn the practical limitations of the technology. The book ends with two chapters that explore a wide range of cryptography applications.

Financial Cryptography and Data Security

This book constitutes the thoroughly refereed post-conference proceedings of the 13th International Conference on Financial Cryptography and Data Security, FC 2009, held in Accra Beach, Barbados, in February 2009.
The 20 revised full papers and 1 revised short papers presented together with 1 panel report and 1 keynote address were carefully reviewed and selected from 91 submissions. The papers are organized in topical sections on economics of information security, anonymity and privacy, private computation, authentication and identification, fraud detection and auctions.

Introduction to Cryptography with Java Applets By David Bishop

Introduction to Cryptography with Java Applets covers the mathematical basis of cryptography and cryptanalysis, like linear diophantine equations, linear congruences, systems of linear congruences, quadratic congruences, and exponential congruences. The chapters present theorems and proofs, and many mathematical examples.
Cryptography with Java Applets also covers programming ciphers, and cryptanalytic attacks on ciphers. In addition, many other types of cryptographic applications, like digest functions, shadows, database encryption, message signing, establishing keys, large integer arithmetic, pseudo-random bit generation, and authentication. The author has developed various Java crypto classes to perform these functions, and many programming exercises are assigned to the reader. The reader should be someone with a basic working knowledge of Java, but having no knowledge of number theory or cryptography.

Codes and Cryptography

This text unifies the concepts of information, codes and cryptography as first studied by Shannon in his seminal papers on communication and secrecy systems. The first five chapters cover the fundamental ideas of information theory, compact encoding of messages and the theory of error-correcting codes. After a discussion of mathematical models of English, there is an introduction to the classical Shannon model of cryptography. This is followed by a brief survey of those aspects of computational complexity needed for an understanding of modern cryptographic methods and the recent advances in public key cryptography, password systems and authentication techniques. Because the aim of the text is to make this exciting branch of modern applied mathematics available to readers with a variety of interests and backgrounds, the mathematical prerequisites have been kept to an absolute minimum. Problems and solutions are include

Complexity and Cryptography, An Introduction

This book originated in a well-established yet constantly evolving course on Complexity and Cryptography which we have both given to final year Mathematics undergraduates at Oxford for many years. It has also formed part of an M.Sc. course on Mathematics and the Foundations of Computer Science, and has been the basis for a more recent course on Randomness and Complexity for the same groups of students.

One of the main motivations for setting up the course was to give mathematicians, who traditionally meet little in the way of algorithms, a taste for the beauty and importance of the subject. Early on in the book the reader will have
gained sufficient background to understand what is now regarded as one of the top ten major open questions of this century, namely the P = NP question. At the same time the student is exposed to the mathematics underlying the security
of cryptosystems which are now an integral part of the modern �email age�. Although this book provides an introduction to many of the key topics in complexity theory and cryptography, we have not attempted to write a comprehensive text. Obvious omissions include cryptanalysis, elliptic curve cryptography, quantum cryptography and quantum computing. These omissions have allowed us to keep the mathematical prerequisites to a minimum. Throughout the text the emphasis is on explaining the main ideas and proving the mathematical results rigorously. Thus we have not given every result in complete generality.
