If you have searched the various .NET help files, you may have encountered encryption examples that always deal with encrypting the contents of a file. This isn't very useful when you need to encrypt something that isn't already contained within a file. In this article, author Brian Patterson covers many of the encryption classes provided in the .NET Framework. Once you've got a grasp on how to use these algorithms, Patterson wraps things up by guiding you through a sample application that will encrypt information before saving it to either a SQL Server or Oracle database server.
About this product: Awarded the 1998 Donald McGannon Award for Social and Ethical Relevance in Communication Policy Research. and Received the IEEE-USA Award for Distinguished Literary Contributions Furthering Public Understanding of the Profession.
Telecommunication has never been perfectly secure. The Cold War culture of recording devices in telephone receivers and bugged embassy offices has been succeeded by a post-9/11 world of NSA wiretaps and demands for data retention. Although the 1990s battle for individual and commercial freedom to use cryptography was won, growth in the use of cryptography has been slow. Meanwhile, regulations requiring that the computer and communication industries build spying into their systems for government convenience have increased rapidly. The application of the 1994 Communications Assistance for Law Enforcement Act has expanded beyond the intent of Congress to apply to voice over Internet Protocol (VoIP) and other modern data services; attempts are being made to require ISPs to retain their data for years in case the government wants it; and data mining techniques developed for commercial marketing applications are being applied to widespread surveillance of the population.
In Privacy on the Line, Whitfield Diffie and Susan Landau strip away the hype surrounding the policy debate over privacy to examine the national security, law enforcement, commercial, and civil liberties issues. They discuss the social function of privacy, how it underlies a democratic society, and what happens when it is lost. This updated and expanded edition revises their original—and prescient—discussions of both policy and technology in light of recent controversies over NSA spying and other government threats to communications privacy.
About this product: In the 1960s, it became increasingly clear that more and more information was going to be stored on computers, not on pieces of paper. With these changes in technology and the ways it was used came a need to protect both the systems and the information. For the next ten years, encryption systems of varying strengths were developed, but none proved to be rigorous enough. In 1973, the NBS put out an open call for a new, stronger encryption system that would become the new federal standard. Several years later, IBM responded with a system called Lucifer that came to simply be known as DES (data encryption standard). The strength of an encryption system is best measured by the attacks it is able to withstand, and because DES was the federal standard, many tried to test its limits. (It should also be noted that a number of cryptographers and computer scientists told the NSA that DES was not nearly strong enough and would be easily hacked.) Rogue hackers, usually out to steal as much information as possible, tried to break DES. A number of "white hat" hackers also tested the system and reported on their successes. Still others attacked DES because they believed it had outlived its effectiveness and was becoming increasingly vulnerable. The sum total of these efforts to use all of the possible keys to break DES over time made for a brute force attack. In 1996, the supposedly uncrackable DES was broken. In this captivating and intriguing book, Matt Curtin charts DES’s rise and fall and chronicles the efforts of those who were determined to master it.
About this product: You know how to build Web service applications using XML, SOAP, and WSDL, but can you ensure that those applications are secure? Standards development groups such as OASIS and W3C have released several specifications designed to provide security - but how do you combine them in working applications?
"Securing Web Services with WS-Security" will help you take your Web services securely to production, with insight into the latest security standards including
- WS-Security, a model that defines how to put security specifications into practice - XML Encryption to ensure confidentiality - XML Signature to ensure data integrity - Security Assertion Markup Language (SAML) to authenticate and authorize users - WS-Policy to set policies across trust domains
Jothy Rosenberg and David Remy, both business, technology, and security visionaries, demystify these standards with practical examples including a fully developed case study application showing these tools at work. A pragmatic approach is taken showing which Web Services Security standards are needed when faced with a variety of security challenges. The authors understand that security remains one of the largest remaining impediments to deploying major Web services in business-critical situations. The goal of this book is to begin to remove those impediments by providing a detailed understanding of all the available security technologies and how and when to employ them.
