122. Survey: Corporate Uses Of Cryptography I haven t heard any answer. 3 Oct 2003 Perth, Australia. cryptography in business? Symmetrickey cryptography. Much is said about keys in cryptography. http://www.viacorp.com/crypto.html

Viacorp.com Free books Who we are FAQ: how we charge ... Site guide How electronic encryption works and how it will change your business WITH STRONG encryption, you can send confidential contracts by email, or safely keep your corporate strategy on a notebook, or take home spreadsheets on a floppy disk. But you need to know what you're doing. I wrote this survey after I'd spent a couple of years helping corporate clients set up secure email systems. Secure email was convenient for us both. Neither of us had to retype anything (compared to the hassles of faxes). And I didn't have to worry about information going to the wrong person by mistake (which happens with faxes). What qualifies me to write on this complex topic? The same thing that might qualify anyone: I have looked into it in detail, stay alert for changes, and I am prepared to be corrected. (And note the small print that comes later). I also have a degree in mathematics, and this is a mathematical subject it is in part, though much about the business use of cryptography is a kind of cultivated common sense. If you're not mathematical, the common-sense side of what I have gathered together here should help. It's common sense I have picked up from those in the know, and it is the bigger part of getting all this right. by Jim Heath of Viacorp Cryptography in business?

Volumes I and II from Aegean Park Press By Randy Nichols (LANAKI) President of the American Cryptogram Association from 1994-1996. Executive Vice President from 1992-1994 Table of Contents Lesson 1 Lesson 2 Lesson 3 Lesson 4 ... Lesson 12 CLASSICAL CRYPTOGRAPHY COURSE BY LANAKI September 27, 1995 LECTURE 1 SIMPLE SUBSTITUTION INTRODUCTION Cryptography is the science of writing messages that no one except the intended receiver can read. Cryptanalysis is the science of reading them anyway. "Crypto" comes from the Greek 'krypte' meaning hidden or vault and "Graphy" comes from the Greek 'grafik' meaning writing. The words, characters or letters of the original intelligible message constitute the Plain Text (PT). The words, characters or letters of the secret form of the message are called Cipher Text (CT) and together constitute a Cryptogram. Cryptograms are roughly divided into Ciphers and Codes. William F. Friedman defines a Cipher message as one produced by applying a method of cryptography to the individual letters of the plain text taken either singly or in groups of constant length. Practically every cipher message is the result of the joint application of a General System (or Algorithm) or method of treatment, which is invariable and a Specific Key which is variable, at the will of the correspondents and controls the exact steps followed under the general system. It is assumed that the general system is known by the correspondents and the cryptanalyst. [FRE1]

Aims to introduce such readers (who may even be very knowledgeable about the applied aspects of cryptography) to the rigorous foundations of the discipline, while attempting to dissolve common misconceptions regarding these foundations.

Home Catalogue Related Areas: Pure Mathematics Computer Sciences New titles email For updates on new titles in: Pure Mathematics Computer Sciences Foundations of Cryptography Volume 1, Basic Tools Oded Goldreich 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.

Quantum Cryptography Tutorial 1. Introduction 2. Standard Cryptography 3. History of Quantum Cryptography 4. Quantum Coding ... 7. References This tutorial was written by James Ford in early 1996. It (and the original version of the accompanying online demo of the BB84 algorithm by Frederick Henle) were created for a class taught by Neal E. Young while he was at Dartmouth College. [Dec. 2003-Jan. 2004: linked to Fred's new demo URL, cleaned up some minor typos, and added this history.] 1. Introduction Quantum cryptography is an effort to allow two users of a common communication channel to create a body of shared and secret information. This information, which generally takes the form of a random string of bits, can then be used as a conventional secret key for secure communication. It is useful to assume that the communicating parties initially share a small amount of secret information, which is used up and then renewed in the exchange process, but even without this assumption exchanges are possible. The advantage of quantum cryptography over traditional key exchange methods is that the exchange of information can be shown to be secure in a very strong sense, without making assumptions about the intractability of certain mathematical problems. Even when assuming hypothetical eavesdroppers with unlimited computing power, the laws of physics guarantee (probabilistically) that the secret key exchange will be secure, given a few other assumptions.

To Home page written by jamesd@echeque.com KongTools.dll. An OLE extension to visual basic, providing elliptic curve cryptographic operations, true random numbers, and Arc4 symmetric key encryption This was written for my own purposes. I wrote it because visual basic is the by far the fastest way of creating a certain kind of program with a reasonably acceptable user interface. However I believe it will be generally useful to anyone who wishes to create a cryptographic program that manages a database, or who merely wants to get a cryptographic program with an attractive user interface up quickly. This code is based largely on the public domain code of George Barwood Paulo S.L.M. Barreto and Steve Reid , as documented in each source file.

ITAR Civil Disobedience (International Arms Trafficker Training Page) From time to time governments make bad laws. One possible way to get a bad law changed is for lots of people to deliberately disobey the law in a public way. This is called civil disobedience Gandhi Martin Luther King Jr. , and many others have used civil disobedience to get bad laws changed. Imagine a bad law saying: "It is O.K. to export books about encryption if they are transported by horse and buggy, but it is illegal to export such books using any motorized vehicle." Crazy? Right! Replace "horse and buggy" with "paper book", and "motorized vehicle" with " machine readable media ", and you get a real law that many Internet users want to get rid of.
