Quantum networking technologies
In recent years, the NCSC has released several documents covering security technologies that rely on quantum mechanics:
in 2016, we published a white paper about Quantum Key Distribution (QKD) .
in 2020, we published a white paper about Quantum Security Technologies , which included thoughts on Quantum Random Number Generation (QRNG) in addition to refined positions on QKD.
Since then, there have been national and international developments.
outlining the NCSC’s approach to quantum security technologies.
The National Quantum Strategy was published in 2022, and implementation of that strategy is underway. The NIST post-quantum cryptography process has defined standards for algorithms that will help manage the threat to cryptography from quantum computing, and standards for common cryptographic protocols are following close behind. And there is a growing consensus among our international cyber security partner agencies around the future direction for quantum communications.
