Abstract In this article, the writer notes that cryptography was a very important element in the results of both World War I and II. The writer points out that while it has been used for centuries for a variety of purposes, cryptography in its currently known forms was first developed during the 17th century. In tracing the work of a variety of cryptographers, this paper shows each contribution during the world wars, and looks at how each success is used as a platform for future achievements in the field. The writer maintains that the pioneering work of the men and women mentioned here is instrumental in the current political climate, where intelligence gathering on terrorism is vitally important.

Decoding the Enigma
From the Paper "Yardley's work here involved receiving encoded messages involving American government officials traveling abroad. He found his work in the Code Room thrilling, and resolved to be involved with cryptography throughout his life.
"With the outbreak of World War I in 1917, Yardley was 28 years old. He was put in charge of Military Intelligence, which required that he decode foreign messages. This was a significant point in American history, as the Intelligence Agency that Yardley set up was the first of its kind in the country. The Agency - MI-8 - proved invaluable to the country. For this, Yardley received the Distinguished Service Medal. Yardley's efforts were used as a springboard for further developments in cryptography during World War II."
Abstract This paper explains the hypotheses of this project, which are: (1) Little can be done to impact a solution's floppy disk speed, (2) SCSI disks no longer affect performance, and (3) much can be done to affect a system's 10th-percentile instruction rate. The author reports, running "Sackbut" on commodity operating systems, such as LeOS and Minix, the experiments proved that exo-kernelizing the saturated online algorithms was more effective than monitoring them. This paper concludes that the author's system sets a precedent for the visualization of robots, and it is expected that cryptographers will improve on Sackbut for years to come. Tables.

Conclusion
From the Paper "Contrarily, this solution is fraught with difficulty, largely due to digital-to-analog converters. Predictably, Sackbut constructs fiber-optic cables. Existing constant-time and classical heuristics use extensible technology to develop the intuitive unification of the partition table and the Turing machine. We view steganography as following a cycle of four phases: synthesis, construction, storage, and emulation. Such a hypothesis is entirely an unfortunate mission but has ample historical precedence. The basic tenet of this solution is the important unification of linked lists and A* search. Combined with the Ethernet, such a claim constructs an analysis of the transistor."
Abstract This paper discusses various concepts regarding information technology security. Specifically, it focuses on denial of service (DOS) attacks and describes measure that can be taken by Internet community members to prevent them. It then looks at digital certificates and signatures and what steps the sender and receiver must take in order to send or receive a digital signature. The paper concludes by discussing cryptographic systems.

SSL/TLS and PPTP as Cryptographic Systems
From the Paper "In the security triad of confidentiality, integrity and availability, extreme implementation to any one of the three will render the two others as weak. Hence, if too much emphasis is put on security by protecting the level of confidentiality availability and integrity of the system will be compromised. If users are given too much access (availability) to the system, then confidentiality will suffer. Although weak cryptographic protocols, SSL/TLS and PPTP are still widely used because they are easy to deploy and implementation is simpler. If the system being protected is not highly confidential, then these three protocols are enough to serve its purpose. For more secure systems, newer and more advanced systems (more difficult to implement) must be used to attain the required level of security."
Abstract This paper examines the issues of copyright infringement and circumvention of technology with reference to the Digital Millennium Copyright Act of 1998. The author of this paper has carefully studied the law in question and has focused on various issues connected with this legislation. DMCA is a highly controversial law that has been staunchly opposed and actively supported by different section of the public and it has managed to attract great deal of media attention because of various lawsuits that emerged in this connection. The paper looks into some important court cases for impartial and objective study of the law.
From the Paper "There has been a long-standing debate on the issue of freedom of speech in the United States. While the Constitution of the country explicitly grants American citizens the right to share information and to speak freely without fear of prosecution through the First Amendment, still both the government and public are confused about the extent to which this legislation is valid and applicable. This is because freedom of speech and the very closely connected issue of copyright infringement have now entered a new realm i.e. the digital world and simply speaking this one domain knew no laws or rules when it first invaded our lives. We need to understand that Internet has on the one hand made access to information easier but on the other hand the same medium has been accused of encouraging copyright violation which has now turned into one of the most heatedly debated issues. Businesses and the general public is not aware of the extent to which they can use copyrighted material available on the Internet while the online companies are puzzled as to what actually constitutes infringement and to what extent can they provide access to such materials to their valued users. With major problems surfacing in this connection, online and digital businesses have been forced to exercise more caution when dealing with copyrighted material."
Abstract This paper analyzes cryptography, the encryption or transformation of data into some unreadable form in order to ensure privacy by keeping the information hidden from anyone for whom it is not intended. It provides a brief overview of cryptography, discusses methods of encryption and description and examines cryptographic protection in Microsoft Windows 2000 as an example of cryptography utilization.
From the Paper "Cryptography is the study of mathematical techniques related to aspects of information security such as confidentiality, data integrity, entity authentication, and data origin authentication. It is defined as the science of protecting data. Cryptographic mechanisms help organizations provide a complete suite of security services. The fundamental goal of cryptography is to adequately address systems and information security in the prevention and detection of cheating and malicious activities."
Abstract This paper explains that the ancient "art" of keeping a secret, cryptography, has joined the age of technology, computerization, and intergalactic communication. The author points out that the government agencies entrusted with maintaining security in the United States have not followed a strictly open path in limiting public access to cryptographic methods. The paper relates that, with the Financial Anti-Terrorism Act, passed in October of 2001, restrictions on surveillance have been reduced, while penalties for low-level computer intrusion are greatly increased.
From the Paper "In the late 1970s, American cryptographers were busy working within the quickly evolving world of the Internet. "This academic revolution--the development of a public science of cryptography and a resulting colloquy about it--was accompanied by a similar, equally dramatic revolution on the microcomputer front. The result: Ordinary people with desk top PCs could encrypt their messages or data to a degree that only governments could have achieved not long before" (Godwin 45). Maintaining secrets had come to be seen as "collecting intelligence", a service provided by a number of government agencies in the United States. Military "intelligence" has also always had the extra burden of maintaining secrets in order to save lives. Probably every nation on earth gathers information concerning the political and military status of other nations."

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 examines how quantum cryptography is a fast growing form of encryption that is not based upon the difficulty of mathematical algorithms and instead employs quantum physics to encrypt information on the physical level. It emphasizes the need for an innovative cipher as well as the need to inform the IT community regarding the commercial application of quantum cryptography. It also provides a broad overview of the quantum cryptographic protocol and operation using fiber optic media.
From the Paper "The integrity of information between sender and receiver relies upon secure channels and more importantly the ability to protect the information from unauthorized recipients. The transmission of information can be compromised when a third party listens in on the transmission media measuring the physical object. Consequently, the eavesdropper can effectively intercept the contents of a communication. Certain types of classical cryptography have proven vulnerable to the interception of data and the incident can remain undetected during the entire transmission. This idea of a man-in-the-middle attack on communication media using quantum cryptography is not possible due to the laws of quantum mechanics. Quantum superposition's and quantum entanglement are two properties of quantum physics used to detect eavesdropping. "
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 This proposal discusses the pervasive adoption of virtual private networks (VPNs) as requiring more organizations to integrate systems, data warehouses and compute-intensive processes together to ensure remote employees, managers, suppliers, and customers have access to the information they need. In many IT architectures the need to integrate with the Windows NTFS Version 3.0, also called the Encrypting File System (EFS) and VPN architectures is becoming commonplace. The intent of this research proposal evaluates the performance of Windows NT-based servers running the NTFS 3.0 with full EFS functionality enabled in a series of benchmarks that replicate actual employee, supplier, and customer work processes. The NetIO and NAS performance benchmarks are used as the basis of comparison.

Technical Comparative Analysis of IPSEC vs. SSL-based VPN
Summary
From the Paper "Comparing the protocols relative to the topologies supported security models used for both session authentication and confidentiality are critical to the security of both IPSEC and SSL-based VPNs. In addition, the major differences in how Quality of Service (QoS) and Service Level Agreements (SLAs) are managed are also highly dependent on the configuration of EFS with both IPSEC and SSL protocols in a VPN environment. The scalability aspects of each protocol are also compared in Table 1 below, in addition to both site-to-site and remote access support from a management perspective is included.
"Provisioning and service deployment as part of VPN management is also included in Table 1. Differences in VPN Client support and transparency are also profiled. Table 1, Technical Analysis of Differences between IPSec and SSL highlight the differences on each of these technical dimensions. The key differences center on scalability and transparency to the user. Scalability of SSL is entirely dependent on the underlying Internet traffic, while in IPSec, through optimized routing of point-to-point connections including the use of algorithms are used to maximize speed."
Abstract The paper discusses the operating system which controls each and every task the computer does. The operating system has various "mindsets", commonly known as "flavors" or types. The most familiar one is the Windows Operating System, which has the Windows XP and the Windows Vista as its current flavors. The paper then states that there are also other operating systems such as the open source Linux and UNIX, but the most important consideration in terms of operating systems are the security features. The paper also briefly outlines the security features for the systems mentioned in the paper. The paper confirms that with the various threats surrounding information systems, security features must be the primary criteria in operating systems usage. The paper concludes that secure and robust operating systems play a key role in keeping a computing environment safe and secure.
From the Paper "Linux is an open source operating system "re-engineered" by Linus Torvalds of Finland. The term re-engineered is used because despite claims that it is not strictly "UNIX," the Linux operating system is based on the UNIX kernel. Between Windows and Linux, there is an ongoing battle of "which is which is better." In terms of usability and commonality features, Windows stands out since this has been the thrust of Bill Gates and company ever since. But Linux - even its desktop variant - seems to be difficult to mange because it is not as commonly used as Windows although it has its truly rewarding security features. In Petreley's 2004 article Security Report: Windows vs. Linux: An Independent Assessment, he lists four key security features of the Linux operating system."
