A More Portable Fortran Random Number Generator

A Perfect Random Number Generator

Portable Random Number Generators

Computers are deterministic devices and a computer-generated random number is a contradiction in terms. As a result, computer-generated pseudorandom numbers are fraught with peril for the unwary. We summarize much that is known about the most well-known pseudorandom number generators: congruential generators. We also provide machine-independent programs to implement the generators in any langua...

"Cracking" a Random Number Generator

[Editor’s Note: This paper was original printed in the January 1977, Volume I, Number 1, issue of Cryptologia (pp. 20-26) the premier issue. Over the years this one article has drawn more interest than any other article and requests for reprints of the paper come in year after year. The editors thought it appropriate to offer this paper to our readers. The original paper was set using WordStar ...

Random Number Generator Recommendation

The generation of uniform pseudo-random numbers between 0 and 1 is important in many numerical simulations. The purpose of this report is to explore the best generator(s) of such random numbers in terms of statistical properties and speed. While attempting to find the best generator in general, the specific goal of this report is to find the best generator for Latin hypercube sampling [Iman and...

Linux Random Number Generator

The venerable Linux /dev/random served users of cryptographic mechanisms well for a long time. Its behavior is well understood to deliver entropic data. In the last years, however, the Linux /dev/random showed signs of age where it has challenges to cope with modern computing environments ranging from tiny embedded systems, over new hardware resources such as SSDs, up to massive parallel system...
