The AllianceCORE ANSI X9.17/X9.31 PRNG, from Helion implements two of the most widely used pseudorandom number generators which may be used to produce encryption keys and IVs for use in hardware implementations of a variety of security protocols. Based on a strong encryption algorithm, and utilising two random inputs - a user supplied random seed value and the current system date/time - the core produces random numbers which meet the requirements of the ANSI X9 standards as recommended by NIST.
