Bøger af Bruce Schneier

A hack is any means of subverting a system's rules in unintended ways. The tax code isn't computer code, but a series of complex formulas. It has vulnerabilities; we call them "loopholes." We call exploits "tax avoidance strategies." And there is an entire industry of "black hat" hackers intent on finding exploitable loopholes in the tax code. We call them accountants and tax attorneys.In A Hacker's Mind, Bruce Schneier takes hacking out of the world of computing and uses it to analyse the systems that underpin our society: from tax laws to financial markets to politics. He reveals an array of powerful actors whose hacks bend our economic, political and legal systems to their advantage, at the expense of everyone else.Once you learn how to notice hacks, you'll start seeing them everywhere-and you'll never look at the world the same way again. Almost all systems have loopholes, and this is by design. Because if you can take advantage of them, the rules no longer apply to you.Unchecked, these hacks threaten to upend our financial markets, weaken our democracy and even affect the way we think. And when artificial intelligence starts thinking like a hacker-at inhuman speed and scale-the results could be catastrophic.But for those who would don the "white hat," we can understand the hacking mindset and rebuild our economic, political and legal systems to counter those who would exploit our society. And we can harness artificial intelligence to improve existing systems, predict and defend against hacks and realise a more equitable world.

Offers a practical guide to achieving security throughout computer networks. This guide provides readers with a better understanding of why protecting information is harder in the digital world, what they need to know to protect digital information, and, how to assess business and corporate security needs.

This text describes Twofish, an algorithm meeting the requirements put forth by the NIST (National Institute of Standards and Technology) for the Advanced Encryption Standard. It also describes the design goals for Twofish, and the building blocks and general design of the cipher.

In "e;Beyond Fear,"e; Bruce Schneier invites us to take a critical look at not just the threats to our security, but the ways in which we're encouraged to think about security by law enforcement agencies, businesses of all shapes and sizes, and our national governments and militaries. Schneier believes we all can and should be better security consumers, and that the trade-offs we make in the name of security - in terms of cash outlays, taxes, inconvenience, and diminished freedoms - should be part of an ongoing negotiation in our personal, professional, and civic lives, and the subject of an open and informed national discussion.With a well-deserved reputation for original and sometimes iconoclastic thought, Schneier has a lot to say that is provocative, counter-intuitive, and just plain good sense. He explains in detail, for example, why we need to design security systems that don't just work well, but fail well, and why secrecy on the part of government often undermines security.  A skeptic of much that's promised by highly touted technologies like biometrics, Schneier is also a refreshingly positive, problem-solving force in the often self-dramatizing and fear-mongering world of security pundits.Schneier helps the reader to understand the issues at stake, and how to best come to one's own conclusions, including the vast infrastructure we already have in place, and the vaster systems--some useful, others useless or worse--that we're being asked to submit to and pay for.

Smart cards have been driven by the need for a secure, portable, computing platform. Hence it is no surprise that security considerations dominated their research. The CARDIS conferences were created to provide a forum for this research. CARDIS 1998 is the third international conference on Smart Card Research and Advanced Applications, held in Louvain-la-Neuve, Belgium, 14-16 Sept- ber 1998. The ?rst CARDIS was held in Lille, France in November 1994, and the second was held in Amsterdam, The Netherlands in September 1996. The fourth CARDIS is scheduled to take place in Bristol, UK in September 2000 (http://www.cardis.org). This volume contains the refereed papers presented at CARDIS 1998. These 35 papers were ?rst published in a pre-proceedings and distributed to the - tendees at the conference; they have subsequently been revised and updated for this volume. The papers discuss all aspects of smart-card research: Java cards, elect- nic commerce applications, e?ciency, security (including cryptographic al- rithms, cryptographic protocols, and authentication), and architecture. Subm- sions from Europe, the U.S., Asia, and Australia show that this is indeed an international area of research, and one that is becoming more popular as pr- tical demand for smart cards increase. We wish to thank the Program Committee members who did an excellent job in reviewing papers and providing feedback to the authors.

Since 1993, cryptographic algorithm research has centered around the Fast So- ware Encryption (FSE) workshop. First held at Cambridge University with 30 attendees, it has grown over the years and has achieved worldwide recognition as a premiere conference. It has been held in Belgium, Israel, France, Italy, and, most recently, New York. FSE 2000 was the 7th international workshop, held in the United States for the rst time. Two hundred attendees gathered at the Hilton New York on Sixth Avenue, to hear 21 papers presented over the course of three days: 10{12 April 2000. These proceedings constitute a collection of the papers presented during those days. FSE concerns itself with research on classical encryption algorithms and - lated primitives, such as hash functions. This branch of cryptography has never been more in the public eye. Since 1997, NIST has been shepherding the Adv- ced Encryption Standard (AES) process, trying to select a replacement algorithm for DES. The rst AES conference, held in California the week before Crypto 98, had over 250 attendees. The second conference, held in Rome two days before FSE 99, had just under 200 attendees. The third AES conference was held in conjunction with FSE 2000, during the two days following it, at the same hotel.
