Quantum key distribution

Information technology - cybersecurity.

(QKD).

Quantum Key Distribution is a mechanism for agreeing encryption keys between remote parties, relying on the properties of quantum mechanics to ensure that key has not been observed or tampered with in transit.

Since traditional public key cryptography algorithms may be vulnerable to a future large-scale quantum computer, new approaches are required that do not share this vulnerability. QKD claims to offer a potential mitigation since its security properties are based on the laws of physics rather than the hardness of some underlying mathematical problems.
