Quantum-powered random numbers could provide key to better cryptography

Are current random number generators ‘good enough’ or should we use quantum technology to achieve better randomness for crypto keys?

Usually when the subject of quantum computing comes up, it’s all rather future-gazing stuff. However, during the Infosecurity Europe 2017 show, one company launched a quantum technology derived product that’s very much here and now: Entropy-as-a-Service.

Whitewood, which is developing crypto-security solutions based on advanced quantum technology, says that the cloud-based service “delivers pure quantum entropy, the foundation of randomness, to generate truly random numbers for creating cryptographic keys that are impossible to guess”.

So how does this work, and do we actually need a quantum random number generator anyway?
