An Introduction to Cryptography provides a solid mathematical treatment of cryptography for readers with little or no background in number theory. Although intended for undergraduate students, it contains enough optional, advanced material to challenge even the most informed reader and provides a solid basis for a second course on the subject. Throughout the book, the author incorporates nearly 300 problems, more than 80 examples, and over 60 diagrams, figures, and tables, as well as optional topics that go beyond the basics. An extensive index, appendices that review background material, and a list of symbols for easy reference complete this outstanding text.

This edition presents the ideas behind cryptography and the applications of the subject. The first chapter provides a thorough treatment of the mathematics necessary to understand cryptography, including number theory and complexity, while the second chapter discusses cryptographic fundamentals, such as ciphers, linear feedback shift registers, modes of operation, and attacks. The next several chapters discuss DES, AES, public-key cryptography, primality testing, and various factoring methods, from classical to elliptical curves. The final chapters are comprised of issues pertaining to the Internet, such as pretty good privacy (PGP), protocol layers, firewalls, and cookies, as well as applications, including login and network security, viruses, smart cards, and biometrics. The book concludes with appendices on mathematical data, computer arithmetic, the Rijndael S-Box, knapsack ciphers, the Silver-Pohlig-Hellman algorithm, the SHA-1 algorithm, radix-64 encoding, and quantum cryptography.

Since the appearance of the authors’ first volume on elliptic curve cryptography in 1999 there has been tremendous progress in the field. In some topics, particularly point counting, the progress has been spectacular. Other topics such as the Weil and Tate pairings have been applied in new and important ways to cryptographic protocols that hold great promise. Notions such as provable security, side channel analysis and the Weil descent technique have also grown in importance. This second volume addresses these advances and brings the reader up to date.

Prominent contributors to the research literature in these areas have provided articles that reflect the current state of these important topics. They are divided into the areas of protocols, implementation techniques, mathematical foundations and pairing based cryptography. Each of the topics is presented in an accessible, coherent and consistent manner for a wide audience that will include mathematicians, computer scientists and engineers.

This book gives a good summary of the current algorithms and methodologies employed in elliptic curve cryptography. The book is short (less than 200 pages), so most of the mathematical proofs of the main results are omitted. The authors instead concentrate on the mathematics needed to implement elliptic curve cryptography. The book is written for the reader with some experience in cryptography and one who has some background in the theory of elliptic curves.

Penetration testing is one of those odd jobs you typically hear little about�it is like a black art, and can come with not only smoke and mirrors but, for the pen tester, any number of trap doors and blind alleys. Bits and pieces of penetration testing have made it into the mainstream media, culminating in the classic hacker-fave film Sneakers, starring Robert Redford, Sidney Poitier, and a host of other stars. And while plenty seems to be written about hacking and gaining access to systems, there has been nothing written that really speaks to the art of penetration testing.

Like most other high tech jobs portrayed in the movies, pen testing is not as glamorous as most people think. Oh sure, there are exciting moments, such as when the first system belonging to the target is penetrated, but it is actually hard work. Comparatively, a typical intruder's job is easy.

A regular electronic intruder has to find only one hole into an organization's computers, but a pen tester has to find them all. This is not only somewhat tedious and even boring at times, it is very important. The intruder probably does not care about such things as accidentally damaging systems, or wiping log files to hide his presence. The pen tester is trying to keep from disrupting normal business, preserve records and logs, yet still trying to move about unnoticed. In other words, to be a pen tester you have to have not only all of the intruder techniques possible, but also understand system administration as well as corporate life in general. Not an easy task.

I wrote this book for software engineers with little or no exposure to cryptography. Most other books fall into one of two categories, the encyclopedia and description or the purely API descriptive. The goal was try and bridge the two by providing a solid introduction to cryptography while providing solid examples and uses. In addition, many books focus overwhelmingly on public key techniques. In my experience the most common uses for public key ciphers are handled by third-party applications (VPNs, Emails) or off-the-shelf protocols such as SSL and SSH.

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 current security methods focus on securing Internet applications using public keys techniques that are no longer effective. In this groundbreaking book, noted security expert Nick Galbreath provides specific implementation guidelines and code examples to secure database and Web-based applications to prevent theft of sensitive information from hackers and internal misuse.

What an amazing world we live in! Almost anything you can imagine can be researched, compared, admired, studied, and in many cases, bought, with the click of a mouse. The Internet has changed our lives, putting a world of opportunity before us. Unfortunately, it has also put a world of opportunity into the hands of those whose motives are less than honorable. A firewall, a piece of software or hardware that erects a barrier between your computer and those who might like to invade it, is one solution.

If you’ve been using the Internet for any length of time, you’ve probably received some unsavory and unsolicited e-mail. If you run a business, you may be worried about the security of your data and your customers’ privacy. At home, you want to protect your personal information from identity thieves and other shady characters. Firewalls For Dummies will give you the lowdown on firewalls, then guide you through choosing, installing, and configuring one for your personal or bus iness network.

Firewalls For Dummies helps you understand what firewalls are, how they operate on different types of networks, what they can and can’t do, and how to pick a good one (it’s easier than identifying that perfect melon in the supermarket.)

Number theory and algebra play an increasingly significant role in computing and communications, as evidenced by the striking applications of these subjects to such fields as cryptography and coding theory. This introductory book emphasises algorithms and applications, such as cryptography and error correcting codes, and is accessible to a broad audience. The mathematical prerequisites are minimal: nothing beyond material in a typical undergraduate course in calculus is presumed, other than some experience in doing proofs - everything else is developed from scratch. Thus the book can serve several purposes. It can be used as a reference and for self-study by readers who want to learn the mathematical foundations of modern cryptography.

It is also ideal as a textbook for introductory courses in number theory and algebra, especially those geared towards computer science students.

This is an outstanding and well-written book whose aim is to introduce the reader to a broad range of material -- ranging from basic to relatively advanced -- without requiring any prior knowledge on the part of the reader other than calculus and mathematical maturity. That the book succeeds at this goal is quite an accomplishment! ...this book is a must-read for anyone interested in computational number theory or algebra and especially applications of the latter to cryptography. I would not hesitate, though, to recommend this book even to students 'only' interested in the algebra itself (and not the computational aspects thereof); especially for computer science majors, this book is one of the best available introductions to that subject.

Aimed at shareware and commercial software programmers, as well as users interested in CD protection, this book will help readers defeat hackers and crackers who try to copy CDs without authorization.

A manual on protecting CDs against illegal copying, this book shows how crackers copy CDs using various access methods. The methods covered include the CDFS driver, cooked mode, SPTI, ASPI, the SCSI port, and the MSCDEX driver. Explained is how to prevent cracker break-ins using protections based on nonstandard CD formats such as the CD driver and weak CD sectors. Information on CD functioning fundamentals and tips related to CD protection in a format free of math and assembling-such as data formats, the scrambler, the Reed-Solomon coder/encoder, the CIRC coder/encoder, and a weak-sectors generator-are also provided. The main program interfaces, which provide direct control via peripheral devices on the application level in UNIX, Novell, and Windows 9x/NT/2000/XP, are considered, as is how to read and write RAW sectors.

The book also discusses practically all commercial CD protection packets available today. It lists their implementation errors, “thanks” to which the copying of protected discs is still possible. The author also suggests several protection mechanisms that take into account his own bitter experience and that of his friends and colleagues. These protection mechanisms cannot be copied using any of the copiers that exist today.

While reading this book, you will learn how to invalidate the disc format in order to make it readable (that is, playable) on most CD-ROM drives, but practically impossible for any copier to copy, and how to bind to the physical disc structure so that copiers are unable either to reproduce or imitate it. You’ll also learn about the physical and technical limitations of low-end recorders and how to use these to achieve your goals.

Finally, the book explains how to create a protected CD copier on your own, making the replication of protected discs a much easier task.

Some security textbooks offer a large dollop of dry useless theory. Reading one of these books is about as exciting as reading a calculus textbook. Other security books offer nothing but a collection of apparently unrelated facts, giving the impression that security is not really a coherent subject at all. Then there are books that present the topic as ac ollection of high-level managerial platitudes. These books may have a place, but if your goal is to design and build secure systems, you’d better understand something about the underlying technology. Finally, some security books focus on the human factors in security. While it is certainly critical to understand the role that human nature plays in security, I would argue that a security engineer must have a solid understanding of the inherent strengths and weaknesses of the technology before the human factors can be fullyappreciated.

Information security is a huge topic, and unlike more established fields, it’s not clear what material should be included in a book like this, or how best to organize the selected material. I’ve chosen to organize this book around the following four major themes:
• Cryptography
• AccessControl
• Protocols
• Software

These themes are fairly elastic so that I can include what I consider to be the most significant material. For example, in my usage, access control includes the traditional topics of authentication and authorization, along with such non-traditional topics as firewalls and CAPTCHAs. The software theme is particularly flexible, including such diverse topics as secure software development, computer viruses, software reverse engineering, and operating systems.

A dirty little secret that vendors don't want you to know is that good computer security doesn't cost a thing. Any solution you can buy is guaranteed to fail. Malicious hackers use this fact to their advantage. Real security is gained by understanding the enemy's tactics and offsetting them with appropriate and consistently applied Windows settings. These expert authors realize that an effective strategy is two parts technology and one part psychology. Along with learning about Vista's new security features (such as UAC, integrity controls, BitLocker, Protected Mode, and IIS 7), learn common-sense recommendations that will immediately provide reliable value.
