An RBG that always has access to an entropy source and (when working properly) produces output bitstrings that have full entropy. Often called a True Random Number (or Bit) Generator.

A USB-pluggable hardware true random number generator. In computing, a hardware random number generator (HRNG), true random number generator (TRNG), non-deterministic random bit generator (NRBG), [1] or physical random number generator [2] [3] is a device that generates random numbers from a physical process capable of producing entropy (in other words, the device always has access to a ...

DRAFT NIST Special Publication 800-90C Recommendation for Random Bit Generator (RBG) Constructions Elaine Barker John Kelsey Computer Security Division

2021年8月9日 · Random numbers have significant applications in fundamental science, high-level scientific research, cryptography, and several other areas where there is a pressing need for high-quality random numbers. We present an experimental demonstration of a non-deterministic random bit generator from a quantum entropy source and a deterministic random bit generator mechanism to provide high quality ...

We describe a minimum entropy justification for the metastable latch based nondeterministic random bit generator (NRBG) also known as an entropy source (ES). The NRBG, used for on-die generation of cryptographic keys in SOCs, is comprised of a CMOS latch with a continuously running offset cancellation loop. The offset cancellation allows for the resolution required to sample device noise at ...
