Countering Detector Manipulation Attacks in Quantum Communication through Detector Self-testing

Abstract

Detector manipulation attacks are the most critical vulnerabilities in practical quantum key distribution systems. We present a self-testing method of photodetectors to reveal manipulation by anything but single photon-level signals, which does not rely on specific assumptions about the detection or manipulation mechanism.
