Abstract

Quantum Key Distribution (QKD) uses Quantum Mechanics to guarantee secure communication. It enables two parties to produce a shared random bit string known only to them, which can be used as a key to encrypt and decrypt messages.

A secret key can be agreed upon even without a central server. For example, Diffie-Hellman Key Exchange is a protocol for agreeing on a secret key based on publicly-discussed very large prime numbers. Its security is based on the assumed difficulty of taking discrete logarithms modulo very large prime numbers. Quantum encryption provides a way of agreeing on a secret key without making this assumption.
