Part of the Integrated .NET Series, this book provides a practical and comprehensive treatment on implementing both cryptography and security features on the .NET platform - using the C# and VB .NET programming languages. It provides focused and detailed code examples that demonstrate the most important concepts, with commentary on how the code examples work. The book also provides a substantial mathematical and theoretical background on the underlying cryptographic concepts. After reading this book and experimenting with the provided example programs, the reader should have a good understanding of the major cryptographic algorithms and standard cryptographic programming techniques. Readers should also gain a solid understanding of how .NET security works and how to implement user-based and code access security in their own .NET programs.

A practical guide to Cryptography and its use in the Internet and other communication networks.
This overview takes the reader through basic issues and on to more advanced concepts, to cover all levels of interest. Coverage includes all key mathematical concepts, standardisation, authentication, elliptic curve cryptography, and algorithm modes and protocols (including SSL, TLS, IPSec, SMIME, & PGP protocols).
* Details what the risks on the internet are and how cryptography can help
* Includes a chapter on interception which is unique amongst competing books in this field
* Explains Public Key Infrastructures (PKIs) - currently the most important issue when using cryptography in a large organisation
* Includes up-to-date referencing of people, organisations, books and Web sites and the latest information about recent acts and standards affecting encryption practice
* Tackles the practical issues such as the difference between SSL and IPSec, which companies are active on the market and where to get further information

Any company using .NET will eventually (if they haven’t already) be exposing part of their functionality as a .NET Web Service, and how to secure these features will become job number one. Web Services security in the .NET Platform will be the comprehensive treatment on how to secure Web Services on the .NET platform and is completely up-to-date for the latest version of Visual Studio .NET. This book specifically focuses on Web Services security, not general .NET security.

OpenBSD ships with an excellent set of Open Source cryptographic tools whose main component is the OpenSSL library and the openssl(1) command-line interpreter. If you need reliable cryptographic tools you will always find them in OpenBSD. And if you need a helping hand when OpenBSD crypto overwhelms you, The Little Book of OpenBSD Crypto Tools is here to show you the shortest path to the right solution. It is a short guide to the OpenBSD cryptographic tools (OpenSSL, swap encryption, partition encryption). It will help you learn how to use OpenSSL to debug your SSL servers, how to use SSL certificates, encryption, and more!

This book deals with how information can disappear so that no one knows of its existence. Convential cryptography merely scambles information into an impenetrable block. This book describes how data can be hidden in the background noise of pictures, sound recording or even bad poetry.Disappearing Cryptography is a collection of mathematical tricks and computational sleights of hand that explore the very foundations of information.

* Visual stenography
* Covers textual cryptoanalysis
* Discusses how to set up networks with hidden communications

OpenSSL is the cryptographic toolkit to use when you need strong, reliable encryption. It is Open Source software, which means that any errors, backdoors, or other problems get discovered and fixed in public, which gives everyone much better protection than commercial, closed crypto tools. If you are a system administrator, who needs to use OpenSSL this book will get you up to speed in the shortest amount of time possible.
This edition discusses OpenSSL tools that ship as a part of the Ubuntu Linux distribution.
Ubuntu ships with an excellent set of Open Source cryptographic tools whose main component is the OpenSSL library and the openssl(1) command-line interpreter. If you need reliable cryptographic tools on a Linux system, you will find them in Ubuntu. And if you need a helping hand when OpenSSL overwhelms you, OpenSSL Crypto Tools. Essential OpenSSL Crypto Skills. Ubuntu Linux Edition, 1st ed. is here to show you the shortest path to the right solution.

This book constitutes the refereed proceedings of the 14th International Conference on Secure IT Systems, NordSec 2009, held in Oslo, Norway, October 14-16, 2009.

The 20 revised full papers and 8 short papers presented were carefully reviewed and selected from 52 submissions. Under the theme Identity and Privacy in the Internet Age, this year's conference explored policies, strategies and technologies for protecting identities and the growing flow of personal information passing through the Internet and mobile networks under an increasingly serious threat picture. Among the contemporary security issues discussed were Security Services Modeling, Petri Nets, Attack Graphs, Electronic Voting Schemes, Anonymous Payment Schemes, Mobile ID-Protocols, SIM Cards, Network Embedded Systems, Trust, Wireless Sensor Networks, Privacy, Privacy Disclosure Regulations, Financial Cryptography, PIN Verification, Temporal Access Control, Random Number Generators, and some more.

The book teaches the reader how to build a complete e-commerce web site written in ASP.NET 3.5 by taking them through the entire design and build process. Uniquely, this book shows how to handle payments through PayPal and DataCash; meaning that the reader is left with a fully functional e-commerce site at the end of the book. The previous edition sold 3,269 copies and still sells 80 a month two years after its release.

Today, computing is dynamic and global. It is no longer practical to input or access data from a single computer. Microsoft .NET Framework allows you to use the same data for various digital devices. However, accessibility can lead to breaches in security. Therefore, this platform also provides several mechanisms for administrators and application developers to protect resources and code from unauthorized users. Microsoft® .NET Framework Security gives you the knowledge to keep your network and code safe and gain the competitive edge!
