Echlon: The Dangers of Communicating in the 21st Century In years past, information was normally considered secure if an individual whispered it to another, or wrote something down on paper. In today's reality, a whisper can be monitored, and your e-mail, even though encrypted, can be intercepted and read. In order to fully explain what ECHELON is and how it came about, we will need to start our journey by going back at least six decades.

Why bother about BIOS security? Security is always only as strong as its weakest link. While there do exist many guidelines to secure various operating systems, there is considerably less material available on how to secure the low-level components of a PC, although these can equally be compromised in order to obtain full control over a machine. First this paper gives an overview of the BIOS and its functions. Then known threats to the BIOS and the hardware of a PC are discussed in detail and how they could be exploited. Finally countermeasures are given that can mitigate the risks.

Overview of S/Key usage with OpenBSD I have been using Open Source Software for quite a while now. Recently I mostly use The OpenBSD Operating System. In my day-to-day work I do a lot of remote administration, well who doesn't? I was getting curious about S/Key usage and integration with the OS for a while, and decided it was a very good time to give it a good test drive. During my tests I used almost exclusively Open Source software. I did use some closed source programs under MS Windows but those were freely available with the OS (telnet.exe, ftp.exe). All other software used and discussed in this paper are Open Source under various licenses. You will witness that you don't need to pay heavy licenses fees to have decent remote access solution.

Java Smart Cards Are Here To Stay: Benefits And Concerns The combination of smart cards plus the Java Card architecture (Java smart cards) could potentially provide millions of consumers with multiple beneficial applications in terms of confidentiality, authentication, integrity and non-repudiation. Nevertheless, as with any new technology, they have stirred up a bit of controversy due to possible privacy issues and lack of a yet broad based understanding and infrastructure. However, smart Java cards seem to be bound to gain momentum and become a permanent fixture of our routine life. In this paper, I will describe the extensive security layers involved in this powerful combination, as well as their vulnerabilities. I will show that benefits seem to outweigh the disadvantages, since certain sectors of society have already accepted the risks.

Cryptography - Business Value Behind the Myth There are many misconceptions about the role cryptography plays in the world of information security. The purpose of this paper is to help information technology professionals make informed decisions about using cryptographic solutions to secure electronic business transactions. The guidance contained in this paper is organized into three main areas of the cryptographic solution life cycle. These three areas can be described as solution discovery, solution integration and solution maintenance. The following provides a consistent approach to cost justify the use of cryptographic security solutions in business applications. Some basic understanding of encryption and cryptography is assumed.

Unlocking the Secrets of Crypto: Cryptography, Encryption, and Cryptology Explained Encryption, decryption and code breaking came into the public consciousness in the 1980s with popularity of the movie War Games. It became newsworthy in the 1990s with the legal battles surrounding PGP and the political discussion of the Clipper Chip. Now, with information security becoming more and more of a common concern, the terms encryption, cryptography and cryptology - commonly grouped together under the term "crypto" - are seeping into our daily language. Still, many people are unsure of what these terms refer to. The purpose of this article is to demystify crypto and break it down to simple tools that aid us in achieving satisfactory privacy and security.

Introduction to Encryption The goal of this article is to present the reader with an introduction to the basics of encryption, its role in the small office/ home office environment and the benefits and drawbacks of encryption to the non-professional user who is concerned about information security.

Digital Signatures and European Laws The European directive is used for business in which European partners (persons or societies) or public administrations are involved. It also means that if an American organization enters into an electronic contract with a European society it has to respect European requirements to ensure the contract is valid. This paper will address these issues and then provide an overview of current trends within various countries in Europe.

Quantum Cryptography This essay can be little out of usual hacking/cracking topic, but I wanted to present you a new technologies that are now used. Also, this tutorial has a 'growing intension' so it will be updated at time to time. The needing for update is mainly here because of need for better explanation because it's hard topic even to those that are familiar with quantum physics and this tutorial is not written for people that are familiar with quantum physics and will give you only basic idea about quantum cryptography. I would be very thankful for any suggestion how to make this tutorial better and clearer because it's very hard to explain some details of quantum theory to people that are not familiar with it. I will be most satisfied if this tutorial can read even my grandmother and get something from it.

Basics of Cryptography I expect you have read one or to papers on cryptography...like everyone else You read, looked confused, felt confused, and a few probably ran away and Cried. Why? Because the encryption used today"s is industrial strength. That"s Because its has to be as our lives rely on information, and so do businesses, So encryption has to stronger than an iron sponge soaked in super glue to keep Our secrets safe. So any papers on the subject start at the top because that is the standard today. But I will start at the beginning (that"s original) so you can learn the Basics of cryptography and build from there.
