Quantum Key Distribution
What is Quantum Key Distribution?
A method of secure communication that uses quantum mechanics principles to create and distribute cryptographic keys that cannot be intercepted without detection.
Frameworks that govern quantum key distribution
What the standards actually require on quantum key distribution
Requirements naming quantum key distribution across 4 standards, quoted from the control text.
NSA does not generally consider quantum key distribution a practical security solution for NSS: it addresses only some threats, performs only key distribution, and needs significant engineering changes to NSS communications.
