%description
The Infinite Noise TRNG is a USB key hardware true random number
generator. It uses what I call a "Modular Entropy Multiplier"
architecture (previously Infinite Noise Multiplier or FireBug). Besides
being simple, low-cost, and fast, it is much easier to get right than
other TRNGs. It naturally defends against influence from outside
signals, such as radio interference and power supply noise, making it
simple to build securely, without requiring an expert in analog design.
Modular entropy multipliers produce a provable and easily measured level
of entropy based on thermal noise, approximately equal to log2(K) per
output bit, where K is a gain between 1 and 2 set by two resistors
around an op-amp. A "health monitor" can track this and verify that the
output entropy is within the expected range, which for the Infinite
Noise TRNG described below is within 2% of log2(1.82).
