A truly random number is something that is surprisingly difficult to generate. A typical approach is to generate the required element of chance from a natural and unpredictable source, such as ...

In this paper, the authors propose the application of cryptography algorithm to ensure secure communication across the virtual networks. In cryptography, encryption is the process of encoding messages ...

Author Nick Sullivan worked for six years at Apple on many of its most important cryptography efforts before recently joining CloudFlare, where he is a systems engineer. He has a degree in mathematics ...

What do you do, when you need a random number in your programming? The chances are that you reach for your environment’s function to do the job, usually something like rand() or similar. This returns ...

A wide variety of applications, including data encryption and circuit testing, require random numbers. As the cost of the hardware become cheaper, it is feasible and frequently necessary to implement ...

Random numbers are useful beasts, in particular for cryptographers who use them to generate their codes. But how best to make random numbers at useful speeds? The question is intimately linked to the ...

Randomness can be a Good Thing. If your system generates truly random numbers, it can avoid and withstand network packet collisions just one of many applications. Here's what you need to know about ...

There will be an app for that: making random numbers on a mobile phone. (Courtesy: Marketa Michalkova) Do you feel nervous when you make a credit-card transaction using your mobile phone? Your worries ...
