qStream QRNG Overview

The strength of your encryption is heavily dependent on the quality of your cryptographic keys.
Our true quantum random number generator (QRNG) qStream™ provides encryption keys with full entropy, i.e. that are truly random. These keys are derived from a quantum source which is unpredictable by nature and are of the highest quality. With a rate of 1 Gbit/sec, the qStream QRNG is the world’s fastest commercial true random number generator  cost-effectively meeting the need for high throughput, quality random for commercial applications whether in enterprise, cloud or shared environments.

The qStream QRNG delivers random numbers for the generation of cryptographic keys and other security parameters, deterministic RNG seeding, initialization vectors, nonces, random challenges, authentication and DSA signing. Other applications include Entropy as a Service (EaaS), simulations, modeling and computer gaming.

Why are random numbers important for data security?


The performance and characteristics of random number generators underlying many security functions have a strong impact on security. To put it simply, attackers don’t crack encryption, they steal or guess keys
