| Summary : High-quality splittable pseudorandom number generator
|
Description :
This package contains an implementation of a high-quality splittable
pseudorandom number generator. The generator is based on a cryptographic hash
function built on top of the ThreeFish block cipher. See the paper /Splittable
Pseudorandom Number Generators Using Cryptographic Hashing/ by Claessen, Pałka
for details and the rationale of the design.
The package provides the following:
* A splittable PRNG that implements the standard \'System.Random.RandomGen\'
class.
* The generator also implements an alternative version of the
\'System.Random.TF.Gen.RandomGen\' class (exported from \"System.Random.TF.Gen\"),
which requires the generator to return pseudorandom integers from the full
32-bit range, and contains an n-way split function.
* An alternative version of the \'Random\' class is provided, which is linked to
the new \'RandomGen\' class, together with \'Random\' instances for some integral
types.
* Two functions for initialising the generator with a non-deterministic seed:
one using the system time, and one using the \'/dev/urandom\' UNIX special file.
The package uses an adapted version of the reference C implementation of
ThreeFish from the reference package of the Skein hash function
(< https://www.schneier.com/skein.html>), originally written by Doug Whiting.
Please note that even though the generator provides very high-quality
pseudorandom numbers, it has not been designed with cryptographic applications
in mind.
