QKD KEY MANAGEMENT SYSTEM

摘要

A system for securely moving data from one location to another exchanges key material between the locations. The system enables cryptosystems to use key material distributed over a quantum channel.

1. A system for providing secure distribution and coordinated access of random bits between a first node and a second node, the first node comprising:
a non-deterministic random bit generator for generating cryptographically strong random bits; a quantum channel connecting the first node to the second node; a quantum key distributor connected to the quantum channel for distributing the generated random bits to the second node; a key storage system for storing the random bits that have been distributed between the two nodes, together with metadata indicative of the generated random bits distributed; and a key management system coupled to the key storage system, allowing external systems to access the random bits while keeping the two nodes synchronised.
