Quantum Key Distribution (QKD)

Quantum key distribution (QKD) is a secure communication method for exchanging encryption keys only known between shared parties.

  • It uses properties found in quantum physics to exchange cryptographic keys in such a way that is provable and guarantees security.
  • QKD enables two parties to produce and share a key that is used to encrypt and decrypt messages. Specifically, QKD is the method of distributing the key between parties.
  • QKD is different from conventional key distribution because it uses a quantum system that relies on basic and fundamental laws of nature to protect the data, rather than relying on mathematics. For ....
