Summary: High-quality splittable pseudorandom number generator |
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.
