qRand™ 100 Entropy Enhancer Overview
The qRand entropy enhancer 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.
The qRand entropy enhancer delivers high speed entropy from the qStream QRNG, our true random number generator, without any changes needed to the application itself.
Are you Entropy Starved?
The qRand entropy enhancer is a unique product which uses our quantum random number generator to feed the entropy pool of Linux systems. This solution guide will walk you through real-world examples of how insufficient entropy can impact performance and security, and how you can address this
