Douglas Stinson - Cryptography: Theory and Practice

Douglas R. Stinson's Cryptography: Theory and Practice is a mathematically intensive examination of cryptography, including ciphers, the Data Encryption Standard (DES), public key cryptography, one-way hash functions, and digital signatures. Stinson's explication of "zero-sum proofs"--a process by which one person lets another person know that he or she has a password without actually revealing any information--is especially good.

If you are new to the math behind cryptography but want to tackle it, the author covers all of the required background to understand the real mathematics here. Cryptography includes extensive exercises with each chapter and makes an ideal introduction for any math-literate person willing to get acquainted with this material.

Description:
Cryptography is an outstanding book that covers all the major areas of cryptography in a readable, mathematically precise form. Several chapters deal with especially active areas of research and give the reader a quick introduction and overview of the basic results in the area. Cryptography provides the mathematical theory that is necessary in order to understand how the various systems work. Most algorithms are presented in the form of pseudocode, together with examples and informal discussion of the underlying ideas. The book gives careful and comprehensive treatment of all the essential core areas of cryptography. Also, several chapters present recent topics that have not received thorough treatment in previous textbooks. Such topics include authentication codes, secret sharing schemes, identification schemes, and key distribution. Amazon.

Introduction to Cryptography

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.

Beginning Cryptography with Java - David Hook

While cryptography can still be a controversial topic in the programming community, Java has weathered that storm and provides a rich set of APIs that allow you, the developer, to effectively include cryptography in applications—if you know how.

This book teaches you how. Chapters one through five cover the architecture of the JCE and JCA, symmetric and asymmetric key encryption in Java, message authentication codes, and how to create Java implementations with the API provided by the Bouncy Castle ASN.1 packages, all with plenty of examples. Building on that foundation, the second half of the book takes you into higher-level topics, enabling you to create and implement secure Java applications and make use of standard protocols such as CMS, SSL, and S/MIME.

What you will learn from this book
- How to understand and use JCE, JCA, and the JSSE for encryption and authentication
- The ways in which padding mechanisms work in ciphers and how to spot and fix typical errors
- An understanding of how authentication mechanisms are implemented in Java and why they are used
- Methods for describing cryptographic objects with ASN.1
- How to create certificate revocation lists and use the Online Certificate Status Protocol (OCSP)
- Real-world Web solutions using Bouncy Castle APIs
Who this book is for
This book is for Java developers who want to use cryptography in their applications or to understand how cryptography is being used in Java applications. Knowledge of the Java language is necessary, but you need not be familiar with any of the APIs discussed.
Wrox Beginning guides are crafted to make learning programming languages and technologies easier than you think, providing a structured, tutorial format that will guide you through all the techniques involved.

Cryptographic Algorithms on Reconfigurable Hardware (Signals and Communication Technology)

Cryptographic solutions using software methods can be used for those security applications where data traffic is not too large and low encryption rate is tolerable. On the other hand, hardware methods offer high-speed solutions making them highly suitable for applications where data traffic is fast and large data is required to be encrypted in real time. VLSI (also known as ASIC), and FPGAs (Field Programmable Gate Arrays) are two alternatives for implementing cryptographic algorithms in hardware. FPGAs offer several benefits for cryptographic algorithm implementations over VLSI as they offer high flexibility. Due to its reconfigurable property, keys can be changed rapidly. Moreover, basic primitives in most cryptographic algorithms can efficiently be implemented in FPGAs.
Since the invention of the Data Encryption Standard (DES), some 40 years ago, a considerable amount of cryptographic algorithm implementation literature has been produced both, for software and hardware platforms. Unfortunately, virtually there exists no book explaining how the main cryptographic algorithms can be implemented on reconfigurable hardware devices.
This book will cover the study of computational methods, computer arithmetic algorithms, and design improvement techniques needed to implement efficient cryptographic algorithms in FPGA reconfigurable hardware platforms. The concepts and techniques to be reviewed in this book will make special emphasis on the practical aspects of reconfigurable hardware design, explaining the basic mathematics related and giving a comprehensive description of state-of-the-art implementation techniques. Thus, the main goal of this monograph is to show how high-speed cryptographic algorithms implementations can be achieved on reconfigurable hardware devices without posing prohibited high requirements for hardware resources.

Foundations of Cryptography: Volume 1, Basic Tools

Cryptography is concerned with the conceptualization, definition and construction of computing systems that address security concerns. This book presents a rigorous and systematic treatment of the foundational issues: defining cryptographic tasks and solving new cryptographic problems using existing tools. It focuses on the basic mathematical tools: computational difficulty (one-way functions), pseudorandomness and zero-knowledge proofs. Rather than describing ad-hoc approaches, this book emphasizes the clarification of fundamental concepts and the demonstration of the feasibility of solving cryptographic problems. It is suitable for use in a graduate course on cryptography and as a reference book for experts.

Cryptography is concerned with the conceptualization, definition and construction of computing systems that address security concerns. The design of cryptographic systems must be based on firm foundations. This book presents a rigorous and systematic treatment of the foundational issues: defining cryptographic tasks and solving new cryptographic problems using existing tools. It focuses on the basic mathematical tools: computational difficulty (one-way functions), pseudorandomness and zero-knowledge proofs. The emphasis is on the clarification of fundamental concepts and on demonstrating the feasibility of solving cryptographic problems, rather than on describing ad-hoc approaches. The book is suitable for use in a graduate course on cryptography and as a reference book for experts. The author assumes basic familiarity with the design and analysis of algorithms; some knowledge of complexity theory and probability is also useful.
