Pseudo Random Number Generator, balanced version (AES256_CTR_DRBG)

Overview

XIP8103B from Xiphera is a Pseudorandom Number Generator (PRNG) Intellectual Property (IP) core. XIP8103B is based on Counter (CTR) operation mode of a 256-bit Advanced Encryption Standard (AES) and uses an AES-CTR implementation as an integral building block.

XIP8103B has been designed for easy integration with FPGA- and ASIC-based designs in a vendor-agnostic design methodology, and the functionality of XIP8103B does not rely on any FPGA manufacturer-specific features.

XIP8103B has also been successfully validated in the CAVP (Cryptographic Algorithm Validation Program) by NIST (National Institute for Standards and Technology).

Key Features

  • Balanced Between Speed and Resource Requirements: XIP8103B can achieve over 2 Gbps throughput, while consuming only about 4000 Lookup Tables (LUTs) in a typical FPGA implementation.
  • Versatility: XIP8103B supports the forward prediction resistance mode, which can be set on and off between output generation, as well as the use of personalization strings and additional inputs for instantiation and reseeding.
  • Standard Compliance: XIP8103B is compliant with the NIST SP800-90A specification.
  • XIP8103B can be combined with Xiphera’s NIST SP800-90Bcompliant XIP8001B to form a NIST SP800-90C compliant Random Bit Generator (RBG).
  • Easy integration with AXI4-lite and AXI stream interfaces.

Applications

  • The main functionality of XIP8103B is to produce pseudorandom numbers. Pseudorandom numbers are numbers which look completely random but which are generated deterministically from a seed If the PRNG is properly seeded with a full-entropy seed (like XIP8001B TRNG) its outputs provide as much randomness, or security, as the seed it was seeded with.
