But for the small business owner, who has minimal understanding of encryption methodologies or terminology, and wants it to stay this way, ease of use is what’s important.

Brief Explanation of Digital Signal Processing, Compression, Encryption, and File Translation by O G Popa
It happens that many people have no idea what Digital Signal Processing means, although they hear more and more often these words, today. Considering the name, Digital Signal Processing, people are lead towards thinking that this procedure deals with digital signals. ... The compression/encryption key--this is in fact another mathematical algorithm--it is responsible for taking the initial digital file and breaking it into frames of integers; for replacing each integer with the number of times it is used; and for storing the code needed to reconstitute the initial series of integers, which...

Why I Hacked My WEP Wireless Router by Paul McGillivary
Part of securing your network must include looking at your wireless access points. Wireless access can be dangerous to your network. Most people don't even know how easy it is to exploit wireless access points. Let me illustrate my point. I went out one afternoon and took my trusty laptop with me. ... I enabled WEP security at 128 bit encryption. ... Remember, I had my WEP encryption set to 128 bits. ... This is a high level of encryption. ... An "open" wireless access point is one that has absolutely no encryption, or security, on the signal.

Video Encryption by Alastair Taylor
What is Video Encryption? Video Encryption is an extremely useful method for the stopping unwanted interception and viewing of any transmitted video or other information, for example from a law enforcement video surveillance being relayed back to a central viewing centre. ... Disadvantages: Can have complex timing control and requires specialized scrambling equipment The cut and rotate video encryption method is probably the best way of achieving reliable and good quality video encryption, an example of a good implementation of this system is in the Viewlock II Implementing vice...

Background: High Definition digital video allows users to experience high resolution, near perfect video content. As more content is delivered digitally, the content creators are increasingly concerned with content piracy because digital content can be perfectly duplicated. ... Stored in the PROM of each transmitter and receiver is an array of 40, 56-bit secret keys and a 40-bit entity called Key Selection Vector. ... Encryption/Transmission : Once authentication is completed, transmission of the video content can commence.

Steganography in Principle by Emmanuel Sodipo
1.0 Introduction Steganography is one of the oldest arts that people have always wanted to have since they started communicating with each other, but sadly the least researched. Most people study steganography either as academic discipline or out of curiosity and I belong to the latter camp. ... This is accomplished by encoding the value of the first secret bit as the parity and the value of the first plus the third cover bit and the second secret bit are xored to form the parity for the second and third cover bit.

Quantum Computing by Michael Cooper
Imagine a computer whose memory is exponentially larger than its apparent physical size; a computer that can manipulate an exponential set of inputs simultaneously; a computer that computes in the twilight zone of space. You would be thinking of a quantum computer. ... In the arguing points, the point that it's potential harm could be that the computational speed would be able to thwart any attempts at security, especially the now NSA's data encryption standard would be useless as the algorithm would be a trivial problem to such a machine.
