### Paper: Why Quantum Cryptography?

Authors: Kenneth G. Paterson Fred Piper Ruediger Schack URL: http://eprint.iacr.org/2004/156 Search ePrint Search Google Quantum Key Exchange (QKE, also known as Quantum Key Distribution or QKD) allows communicating parties to securely establish cryptographic keys. It is a well-established fact that all QKE protocols require that the parties have access to an authentic channel. Without this authenticated link, QKE is vulnerable to man-in-the-middle attacks. Unfortunately this fact is frequently overlooked, resulting in exaggerated claims and/or false expectations about the potential impact of QKE. In this paper we present a systematic comparison of QKE with traditional key exchange protocols in realistic secure communication systems.
