qRand™
Quantum Entropy Injector

Feeds quantum random numbers to the entropy pool of your computer, solving the problem of “entropy starvation”. Your applications will always have sufficient entropy, even in virtual environments.

Product Sheet

qRand Overview

qRand monitors a computer’s entropy pool and augments it with full entropy random bits
when necessary, solving the problem of “entropy starvation”. This prevents
performance degradation and the security compromise of using low entropy pseudo-randomness.

qRand delivers high speed entropy from qStream, our true random number generator,
without any changes needed to the application itself.

qRand in Practice


Learn more about our quantum entropy injector and how it uses quantum random numbers to feed the entropy pool of a Linux system in this blog post that explores real-world examples.
