Use of the Internet is expanding beyond anyone's expectations. As corporations, government offices, and ordinary citizens begin to rely on the information highway to conduct business, they are realizing how important it is to protect their communications -- both to keep them a secret from prying eyes and to ensure that they are not altered during transmission. Encryption, which until recently was an esoteric field of interest only to spies, the military, and a few academics, provides a mechanism for doing this. PGP, which stands for Pretty Good Privacy, is a free and widely available encryption program that lets you protect files and electronic mail. Written by Phil Zimmermann and released in 1991, PGP works on virtually every platform and has become very popular both in the U.S. and abroad. Because it uses state-of-the-art public key cryptography, PGP can be used to authenticate messages, as well as keep them secret. With PGP, you can digitally "sign" a message when you send it. By checking the digital signature at the other end, the recipient can be sure that the message was not changed during transmission and that the message actually came from you. PGP offers a popular alternative to U.S. government initiatives like the Clipper Chip because, unlike Clipper, it does not allow the government or any other outside agency access to your secret keys. PGP: Pretty Good Privacy by Simson Garfinkel is both a readable technical user's guide and a fascinating behind-the-scenes look at cryptography and privacy. Part I, "PGP Overview," introduces PGP and the cryptography that underlies it. Part II, "Cryptography History and Policy," describes the history of PGP -- its personalities, legal battles, and other intrigues; it also provides background on the battles over public key cryptography patents and the U.S. government export restrictions, and other aspects of the ongoing public debates about privacy and free speech. Part III, "Using PGP," describes how to use PGP: protecting files and email, creating and using keys, signing messages, certifying and distributing keys, and using key servers. Part IV, "Appendices," describes how to obtain PGP from Internet sites, how to install it on PCs, UNIX systems, and the Macintosh, and other background information. The book also contains a glossary, a bibliography, and a handy reference card that summarizes all of the PGP commands, environment variables, and configuration variables.

No, you are not paranoid. They are out to read your email. In this engaging and oddly reassuring text, practitioner Lucas describes Pretty Good Privacy (PGP) and Open Source GPG for moderately skilled computer geeks who are unfamiliar with public-key cryptography but want a cheap solution to security woes. He covers cryptography, installing OPENPGP

Studienarbeit aus dem Jahr 2002 im Fachbereich Informatik - Sonstiges, Note: 6.0 (CH-Notensystem; D: 1.0), Eidgenossische Technische Hochschule Zurich (Informatik), Sprache: Deutsch, Anmerkungen: Uberblick uber PGP (Funktionsweise und Sicherheit). Schlusselmanagement Angriffsszenarien und deren Abwehr. Diskussion uber den Sinn starke Verschlusselung der breiten Masse zuganglich zu machen respektive einzuschranken oder zu verbieten., Abstract: Eine Arbeit uber Nutzen und Gefahren uber den freien Zugang starker Verschlusselung fur die Gesellschaft. Aufzeigung wie PGP funktionniert sowie wo dessen Grenzen und Gefahren sind. Abstract Der Austausch digitaler Informationen ist ein wesentlicher Teil unserer Gesellschaft geworden. Zudem ist Information heute eine wertvolle Ressource. Aufgrund der hohen Transparenz des Datenverkehrs via Internet ist Datenschutz fur viele doppelt wichtig geworden. Privat-Unternehmen, Arzte, Anwalte sowie Privat-Personen sind heute ebenfalls wie Banken, der Staat, das Militar auf eine schnelle Kommunikation, wie sie in digitaler Form via Internet moglich ist, angewiesen. Dies, um Entscheide treffen zu konnen usw. Es besteht reges Interesse daran, dass nur der Empfanger die Nachricht zu lesen bekommt, respektive dass die Privatsphare geschutzt bleibt. Philip Zimmermann hat mit der Erfindung von Pretty Good Privacy, kurz PGP, eine Moglichkeit geschaffen, mit welcher selbst Computerlaien ihre Daten, welche uber Netze kommuniziert werden, schutzen konnen. So hat jedermann die Moglichkeit seine Privatsphare, den Daten- und Meinungsaustausch sowie Geschaftsabwicklungen zu schutzen. Diese Arbeit gibt einen Uberblick uber PGP. Die Funktionsweise und die Sicherheit werden vertieft betrachtet und es wird aufgezeigt, wie PGP das Schlusselmanagement anpackt. Sie diskutiert Angriffsszenarien und zeigt Moglichkeiten auf, diese abzuwehren oder zu verhindern. In einer Schlussdiskussion wird der Frage nachgegangen, wie sinnvoll es ist, starke Ver

In his first book since the bestselling Fermat's Enigma, Simon Singh offers the first sweeping history of encryption, tracing its evolution and revealing the dramatic effects codes have had on wars, nations, and individual lives. From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy. Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world's most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.

The book details how programmers and electronic communications professionals can use cryptography-the technique of enciphering and deciphering messages-to maintain the privacy of computer data. It describes dozens of cryptography algorithms, gives practical advice on how to implement them into cryptographic software, and shows how they can be used to solve security problems. Covering the latest developments in practical cryptographic techniques, this new edition shows programmers who design computer applications, networks, and storage systems how they can build security into their software and systems. What's new in the Second Edition? * New information on the Clipper Chip, including ways to defeat the key escrow mechanism * New encryption algorithms, including algorithms from the former Soviet Union and South Africa, and the RC4 stream cipher * The latest protocols for digital signatures, authentication, secure elections, digital cash, and more * More detailed information on key management and cryptographic implementations
