Abstract
This document discusses a case in which an editor, Alice, and a reporter, Bob, exchange data encryption keys with a source, Charlie, and utilize this data encryption method as a secure way to exchange information. Alice does not trust the encryption protocol and is demanding Bob produce some sort of physical or tangible evidence it was in fact Charlie who encrypted and sent a digital message. The paper further discusses how this demand undermines the entire purpose of encrypting the data in the first place if one is going to doubt the origin of the data following the implementation of encryption procedures.
From the Paper
"Alice is an editor for a major newspaper while Bob is a reporter for that same newspaper. Bob's contact, Charlie, is an executive for a major corporation and regularly provides Bob with proprietary information. Alice, Bob and Charlie collectively agreed to exchange information electronically after mediating that data through encryption technology. This process works in several ways to ensure the data and information retains its integrity: 1) because the encryption key is known only to the relevant parties, the data or information is effectively assured of originating from the relevant parties, and 2) because it is encrypted in a sophisticated manner, the data or information is incredibly secure as it would take an even more sophisticated program and programmer to un-encrypt it."

From the Paper
"Computer encryption is based on the science of cryptography (Tyson, 2000), which has been used since the days of the Roman Empire. Prior to the technological age, the governments used cryptography for military purposes. The existence of coded messages dates back to the Roman Empire. However, most forms of modern cryptography are based on computers, simply because a human-based code is relatively easy for a computer to crack."

Abstract
This paper examines how the needs of the e-commerce community and of the nation to protect itself must both be taken into consideration if the nation is to create a balanced and mutually beneficial approach to improving Internet security. It explores how the market is demanding improved and easier to use encryption technology and how the Government wants to limit, or at least guide, the availability of the same. It looks at how the development of public policy and corporate behavior that can satisfy both is the key to making advancement in encryption technology available to the masses.
From the Paper
"The science of cryptography offers many potential solutions to the drawbacks of early copy protection schemes, and the operative word is ?potential?. Cryptography has long been used by military and intelligence agencies to transmit messages so that foreign governments could not decipher them. (Fleischmann 1995) As early as the second world war, the US and foreign governments utilized encryption schemes in order to disguise their communications. Simple encryption is the process of scrambling readable text to make it unreadable based on a key known only to the sender and the receiver. Decryption, on the other hand, is the unscrambling process which occurs on the other end."

Abstract
This paper examines how there are several legal issues come into play when attempting to protect consumers who use the Internet and how one such method of protection is through encryption and cryptography of information. It looks at how encryption and cryptography of information prevents unwanted persons from accessing information or if access is gained, from reading and understanding messages that are not intended for them. The paper also examines how, although legal actions may be taken to protect consumers, many actions are available that consumers can make on their own to protect themselves and their businesses.
From the Paper
"In ancient times encryption was used by those individuals who had an exceptional need for confidentiality and were willing to put in the effort required to do so such as those involved in trading. The use of encryption during World War II is also documented. As use of the encryption system grew and improved over the years, the implementation of the U.S. Data Encryption Standard (DES) and public key cryptography in the 1970's brought about the emergence from the preserve of secretive government agencies into the public domain. "Data Encryption Standard (DES) is a widely-used method of data encryption using a private (secret) key that was judged so difficult to break by the U.S. government that it was restricted for exportation to other countries (Biasci, Granum & Randatz). Protecting military secrets has historically been done my encrypting messages so they can be read only by the intended recipient. "

Abstract
This paper looks at how vital this form of technology is. It discusses the spread of the use of internet for doing day-to-day transactions such as bill paying and purchases - and how this has created the need for the protection of sensitive data from being misused. The paper examines the history of encryption technology and how it developed into the level it is today. The issue of the need for privacy in the cyberworld is also discussed.
From the Paper
"The Internet has made the transfer of data easy and has become an everyday part of our lives. Many of us could not even imagine our lives without the Internet, let alone, the computer. Computers allow us to store and transmit data with ease. Data storage takes up much less space than a filing cabinet and data can be transmitted almost instantaneously using the Internet. The ease and speed of data transfer has led to the development of faster and bigger systems to handle larger and larger amounts of data. Some of this data is private and contains information that is only to be read by certain individuals. Now we transmit critical information such as credit card and banking information over the Internet on a daily basis. So how do we protect that information from prying, but unauthorized eyes? Encryption is one technique used to protect the data."

"Encryption and Hash Algorithms
Introduction
Stephen Levy (2001), reporting on the latest ?unbreakable code? begins his report by quoting Edgar Allan Poe. ?It may roundly be asserted that human ingenuity cannot concoct a cipher which human ingenuity cannot resolve? (Levy, 2001, 45). This article was selected to lead off this discussion of encryption because of two elements of confusion.
First, the headline read ?An Unbreakable Code?? and the article was about enciphering and deciphering, also called ?encryption? and ?decryption.? This is a common, and often-repeated mistake, one which can confuse the very field of study. A ?code? is not a ?cipher? anymore than a ?tennis ball? is a ?cabbage.?
A code is a..."

Abstract
This paper describes and analyzes various methods of computer encryption that are used to protect data as it traverses the Internet. The author describes how data and information packets going through cyberspace are susceptible to interception and compromise. Several programs that protect data are described, including DES, RSA, AES, Blowfish and ECC. The author reviews these packages, and concludes that despite the availability of several cryptosystems in the market, security should still be based on the needs of the situation
From the Paper
"Aside from DES and RSA, other crypto solutions are Blowfish, ECC and AES. Blowfish is a block cipher using 32 to 448 bits long keys. The data blocks go through 16 rounds of cryptographic functions (Staron and Adams, 2001) and the technique was designed by Bruce Schneier "to be immune to linear and differential cryptanalysis (Staron and Adams, 2001)." Ellipse Curve Cryptosystems (ECC) is similar to RSA in terms of providing both digital signature and encryption. By using properties of elliptic curves, ECC "provide ways of constructing groups of elements and specific rules on how the elements within these groups combine. One differing factor of ECC is its efficiency since it could work with limited processing capacity, storage supply, and bandwidth (Harris, 2003)," which makes it a good solution for wireless and mobile technologies."

Abstract
The rapid advancement of technology, particularly in the telecommunication and computer sector, has brought a paradigm shift to our communication methodology. The Internet has revolutionized the world of communication, and today we are living in a global village without any geographical limitations. This paper shows that the change in business methodology indicated by the unprecedented growth of e-commerce is not without its problems. The loopholes in the new technology provide a fertile ground for miscreant elements. Hackers are on the increase, and the Net seems not all that safe and confidential. This paper discusses cryptography, which is the science of data encryption, a technology that provides for a safe, secure, and private information exchange. Cryptography has evolved from its primitive form, and today it is studied as a separate subject. Encryption has become an integral part of our security provisions, and it provides for safe transmissions through a path infested with hackers and snoopers and other kinds of offenders who use their technical expertise to intrude into and threaten the privacy and confidentiality of our vital data. The paper discusses the application of cryptography, with a brief overview of the basic mathematics and the different algorithms.

From the Paper
"Block ciphers operate on a block of plain text and encrypt them with a key of a particular length to yield a block of cipher text. For this purpose the given string is divided into blocks and encryption algorithm is applied to the individual blocks. The DES is currently one of the best-known block ciphers and also the standard followed by the American government for the past twenty years. Obviously problems arise when we try to use the same crypto key for identical blocks of plain text. This reveals clear pattern in the transmitted cryptogram making it easy for the hacker to decrypt the message. The essential property of a successful algorithm is the need to produce cryptograms without any obvious patterns that can be related to the individual blocks of the plain text."

Abstract
This document discusses the case of Alice, a high net worth customer of the Modern Security Trust Bank in which she had significant deposits. Alice constructed an encryption device based on RST encryption technology and gave the public key encryption to Frank at the bank. She kept the private key in her residence. Frank claims to have received an order to transfer a $1,000,000 to his personal bank account from Alice's bank account upon her instructions. This is an instruction that Alice claims to never have given and she insists that Frank produced the encrypted message himself. The paper explains how, on the the surface, this case appears to be a simple one of bank fraud and breech of fiduciary trust, but it is complicated by the presence of an active data encryption solution (RSA) that ensures all transactions are legitimate or are intended to be legitimate within the context of the human organization within in which it is meant to function.
From the Paper
"Modern Security Trust (MST) is a technology dependent banking institution that caters to net-worth individuals as well as clients with less spectacular incomes. At issue is a $1,000,000 deposit withdrawn from Alice, a high net-worth client of MST which was, in turn, deposited into a bank account in the Caribbean island of Nevis where it was discovered that the bank account was owned by an MST employee entrusted with the security of Alice's account."

Abstract
This paper explains that the key Internet issues of Internet security and privacy arise because of the anonymous nature of the Web. The author points out that cookies are nothing but small pieces of data that are stored on the hard disk of the user and are used primarily for storing the settings for the Web pages as per the user?s interest. The paper stresses that children are more prone to let out their personal information when they surf the Net and can accidentally come across offensive Web pages with vulgar, pornographic contents.

Conclusion
From the Paper
"Man-In-Middle Attack is another form of information abuse in which a third party intercepts information flow between two computers and alters the data. Typically, this attack is carried out by mocking a well-known website. A practical example of this type of ?spoofing? was the 1999 incident when a website spoofed as Bloomberg News service, posted information that ?Pairgain?, a telecommunication company was being taken over by an Israeli firm. This falsified information posted on the counterfeit website sent the stock trading up by 30% and the trading volume grew by 7 times its usual. However when the hoax came to light the stock prices plummeted down resulting in huge losses to investors who bought the shares at inflated prices. This example highlights the serious consequences of internet crime."

Abstract
Kids decoder rings in cereal boxes, the puzzles in the comic pages of the daily newspapers and high-tech encryption all have something in common, they are all variations of cryptography. The paper shows how, ever since the early days of civilization, people have been trying to encode massages to keep secrets from falling into the hands of the wrong person. Today the science and math of cryptography go way beyond switching letters around according to a certain pattern, but if a person remembers that the basic idea is the same, cryptography can be a fascinating endeavor into math, science, and even into language itself. This paper reviews the history of cryptography and the many things encryption has been used for in the past. It then looks at how encryption is used in modern times and for what purposes. The paper explains cryptography from a mathematical point of view, following the development of encryption and cryptography mathematically. Finally, it looks at the future of this science.
From the Paper
"One of the most important developments came in the form of the Wheel Cipher. The Wheel Cipher was created by Thomas Jefferson, possibly with the help of Dr. Robert Patterson, a mathematician at the University of Pennsylvania. In 1913, Captain Parket Hitt reinvented the Wheel Cipher in strip form. This lead to the creation M-138 -A, used in World War II. Just a few years later in 1916, Major Joseph O. Mauborgne ut Hitt?s strip cipher back into the wheel form, strengthened the alphabet construction, and produced the device that would lead to the M-94 cipher device. These devices, along with encryption courtesy of the Navajo people, helped the allies defeat Germany, Japan, and Italy in World War II."

"TRANSACTION SECURITY ON THE INTERNET
Introduction
Security is one of the primary concerns when an organization connects its private network to the Internet (Rowe, 1998, 26). In 1995, 1290 network managers reported financial losses due to ineffective network security (Lopez, 1996, 41). Twenty percent of those respondents indicated that breaches in network security stemming from Internet connections were to blame.
Increasing numbers of private networks need access to Internet services, and corporations want to offer Web access to their current and potential customers. To achieve this, an organization needs the protection that a SET (Secure Electronic Transaction) can provide (Maglitta & Booker, 1994, 79). There are many parts to an SET."

"The purpose of this research is to examine the issues concerning government security. The plan of the research will be to set forth the context in which the subject of governmentrelated security measures of various kinds has achieved importance, and then to discuss the variety of views, some of them controversial, surrounding such subsidiary topics as document control and destruction, security predicated of the government's view of one's so-called need to know, legal and ethical issues in regard to mailing and reproduction of documents, and such issues of access control as personnel identification, whether by badges or other means.
There appears to be an inherent tension between the idea of democracy and the idea of government security in the modern period, for the boundaries between what democratic values a ... "
