Fast NIST ESV certified, FIPS (SP800-90A/B/C) True Random Number Generator

Overview

Key Features

• Non-deterministic Random Number Generator, FIPS-140 SP800-90A/B compliant, ESV certified for NRBGs and DRBGs (#E225).
• High performance, low power, fully digital, standard cell only, supports all CMOS nodes.
• Available as standalone RBG or embedded in the Rambus RT-130, RT-630, RT-660 Root of Trusts

Benefits

• This patent-protected TRNG implementation has all the noise-accumulation benefits of traditional free-running oscillators, but also adds non-traditional source of entropy: a bi-directional ring of chaotic pattern generators. This novel ring topology creates bi-directional constructive/destructive interference of the waveform, resulting in very fast time-to-max-entropy, and very high entropy generation rates. Compared to free running oscillator-based entropy sources, this RBG core has other advantages such as inherent resistance to simple noise injection locking, and minimized need for oscillator calibration and/or noise isolation during implementation.
• The TRNG-IP-77 is a security aware design:
  • SP 800-90B entropy source, digital 2-ring Chaotic Random Number Generator.
  • SP 800-90A AES CTR mode based post processing
  • Selectable reseed interval
  • Built-in health tests
• The TRNG-IP-77 is compliant with Federal Information Processing Standards (FIPS) Publication 140-3, facilitating system certification. The design is compliant with the latest versions for NIST SP800-90A/B/C. A NIST SP800-90A Deterministic Random Bit Generator (DRBG) is available for the required post processing. The TRNG-IP-77 is ESV certified and is FIPS-approved when integrated into Rambus Root of Trust solutions.
• The TRNG-IP-77 is silicon proven, and its flexible, layered design makes it easy to integrate into SoCs.
