Enhancing Quantum Key Distribution (QKD) to address quantum hacking
Procedia Technology, 2012 AbstractQuantum key distribution (QKD) is intended to produce cryptographic secret keys between two remote parties, usually called Alice and Bob. Even though QKD has been proven to be unconditionally secure against the eavesdropper, commonly called Eve, practical implementations of QKD may contain vulnerabilities that may lead to the generated secret ...
