General Purpose PRNGDES

  • Technology Overview

General Purpose Pseudo Random Number Generator is a deterministic random bit generator (DRBGs). DRBGs, sometimes called deterministic random number generators or pseudorandom number generators, use cryptographic algorithms and the associated keying material to generate random bits. Random number generators (RNGs) are required for the generation of keying material (e.g., keys and IVs).

  • Product Features

    • Generates pseudo random number for General purpose X-change DES of "FIPS PUB 186-2 (+change notice)", Federal Information Processing Standards Publication, 2000 January 27.
    • APIs for XKey initialization, XSeed initialization and Pseudo random number generation.
    • Flexible interface with 'C' callability.
    • Easily portable to other architectures.
    • The code is interruptible and fully re-entrant. It can be used in systems with multi threaded software architecture.

  • Processor

    • ARM-7TDMI with 8KB unified cache and 64 MHz clock.
