The quantum-mechanical background needed to present some fundamental protocols from quantum cryptography is provided, and quantum key distribution via the BB84 protocol and its security proof are reviewed.
Abstract
We survey some results in quantum cryptography. After a brief introduction to classical cryptography, we provide the quantum-mechanical background needed to present some fundamental protocols from quantum cryptography. In particular, we review quantum key distribution via the BB84 protocol and its security proof, as well as the related quantum bit commitment protocol and its proof of insecurity.
