However, most of the books currently available on the subject are aimed at practitioners who just want to know how the various tools available on the market work and what level of security they impart. These books traditionally deal with the science and mathematics only in so far as they are necessary to understand how the tools work. Internet Security differs by its assertion that cryptography is the single most important technology for securing the Internet. To quote one reviewer "if every one of your communication partners were using a secure system based on encryption, viruses, worms and hackers would have a very hard time". This scenario does not reflect the reality of the Internet world as it currently stands. However, with security issues becoming more and more important internationally, engineers of the future will be required to design tougher, safer systems. Internet Security: * Offers an in-depth introduction to the relevant cryptographic principles, algorithms protocols - the nuts and bolts of creating a secure network * Links cryptographic principles to the technologies in use on the Internet, eg. PGP, S/MIME, IPsec, SSL TLS, Firewalls and SET (protecting credit card transactions) * Provides state-of-the-art analysis of the latest IETF standards plus summaries and explanations of RFC documents * Authored by a recognised expert in se Read more...

Only a few years ago quantum cryptography – or better: quantum key distribution (QKD) – was the domain of basic research laboratories at universities. But during the last few years things changed. QKD left the laboratories and was picked up by more practical oriented teams that worked hard to develop a practically applicable technology out of the astonishing results of basic research. One major milestone towards a QKD technology was a large research and development project funded by the European Commission that aimed at combining quantum physics with complementary technologies that are necessary to create a technical solution: electronics, software, and network components were added within the project SECOQC (Development of a Global Network for Secure Communication based on Quantum Cryptography) that teamed up all expertise on European level to get a technology for future encryption. The practical application of QKD in a standard optical fibre network was demonstrated October 2008 in Vienna, giving a glimpse of the future of secure communication. Although many steps have still to be done in order to achieve a real mature technology, the corner stone for future secure communication is already laid. QKD will not be the Holy Grail of security, it will not be able to solve all problems for evermore. But QKD has Read more...

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.

With these changes in technology and the ways it was used came a need to protect both the systems and the information. For the next ten years, encryption systems of varying strengths were developed, but none proved to be rigorous enough. In 1973, the NBS put out an open call for a new, stronger encryption system that would become the new federal standard. Several years later, IBM responded with a system called Lucifer that came to simply be known as DES (data encryption standard). The strength of an encryption system is best measured by the attacks it is able to withstand, and because DES was the federal standard, many tried to test its limits. (It should also be noted that a number of cryptographers and computer scientists told the NSA that DES was not nearly strong enough and would be easily hacked.) Rogue hackers, usually out to steal as much information as possible, tried to break DES. A number of "white hat" hackers also tested the system and reported on their successes. Still others attacked DES because they believed it had outlived its effectiveness and was becoming increasingly vulnerable. The sum total of these efforts to use all of the possible keys to break DES over time made for a brute force attack. In 1996, the supposedly uncrackable DES was broken. In this captivating and intriguing book, Matt Curtin charts DESs rise and f Read more...

Cryptography is the gold standard for security. It is used to protect the transmission and storage of data between two parties by encrypting it into an unreadable format. Cryptography has enabled the first wave of secure transmissions, which has helped fuel the growth of transactions like shopping, banking, and finance over the world's biggest public network, the Internet. Many Internet applications such as e-mail, databases, and browsers store a tremendous amount of personal and financial information, but frequently the data is left unprotected. Traditional network security is frequently less effective at preventing hackers from accessing this data. For instance, once-private databases are now completely exposed on the Internet. It turns out that getting to the database that holds millions of credit card numbers-the transmission-is secure through the use of cryptography, but the database itself isn't, fueling the rise of credit card information theft. A paradigm shift is now under way for cryptography. The only way to make data secure in any application that runs over the Internet is to use secret (also known as private) key cryptography.

The book is worth buying. Review: This book is a very readable introduction to the theory of numbers. The author manages to concentrate in a relatively short book and with a very clear and pleasant style the material necessary to understand the mathematics underneath the RSA cryptosystem. No previous knowledge of advanced mathematics is assumed. Perhaps not enough for mathematicians, but more than rewarding for the rest of us. It reminds me a bit of the style of M. Gardner. Books on mathematics can be very dull without the style of exposition of Mr. Coutinho. Highly recommended ! Review: all about understanding RSA The book revolves around RSA. The motivation for the book is that the reader wants to understand public/private key cryptography, where this is represented by the seminal RSA algorithm. The author assumes little previous acquaintance with number theory on your part. He develops his arguments from this minimal background. So modular arithmetic is introduced, and thence such key ideas as groups, primality tests, Chinese Remainder Theorem and, finally, the RSA cryptosystem.

Coding theory provides explicit ways of ensuring that messages remain legible even in the presence of errors. Cryptography on the other hand, makes sure that messages remain unreadable | except to the intended recipient. These complementary techniques turn out to have much in common mathematically. The syllabus for the course is dened by the Faculty Board Schedules (which are minimal for lecturing and maximal for examining). I should very much appreciate being told of any corrections or possible improvements and might even part with a small reward to the rst nder of particular errors. This document is written in LATEX2e and stored in the le labelled ~twk/IIA/Codes.tex on emu in (I hope) read permitted form. These notes are based on notes taken in the course of the previous lecturer Dr Pinch. Most of their virtues are his, most of their vices mine. Although the course makes use of one or two results from probability theory and a few more from algebra it is possible to Read more...

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 and 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 Read more...

It’s called cryptovirology, the art of turning the very methods designed to protect your data into a means of subverting it. In this fascinating, disturbing volume, the experts who first identified cryptovirology show you exactly what you’re up against and how to fight back. They will take you inside the brilliant and devious mind of a hacker—as much an addict as the vacant-eyed denizen of the crackhouse—so you can feel the rush and recognize your opponent’s power. Then, they will arm you for the counterattack. This book reads like a futuristic fantasy, but be assured, the threat is ominously real. Vigilance is essential, now. * Understand the mechanics of computationally secure information stealing * Learn how non-zero sum Game Theory is used to develop survivable malware * Discover how hackers use public key cryptography to mount extortion attacks * Recognize and combat the danger of kleptographic attacks on smart-card devices * Build a strong arsenal against a cryptovirology attack Review “The authors of this book explain these issues and how to fight against them.” (Computer Law and Security Report, 1st September 2004) Read more...
