Random numbers are important in many areas of computing. A very important
approach to generating random number sequences is Pseudo-Random Number
Generators. Robert Stone gives an overview of Pseudo-Random Number Generation,
with some explanation of Cryptographically Secure Pseudo-Random Number
Generators. He also discusses some of the ways this can go wrong, including
examples from recent security news. He finishes up with information about Perl
modules that can be used for generating Pseudo-Random Number Sequences.
