Abstract
Disclosed herein are an apparatus and method for mutual authentication of quantum entities based on Measurement-Device-Independent Quantum Key Distribution (MDI-QKD). The method may include configuring a quantum input form based on an authentication key shared in advance with a counterpart entity, applying polarization modulation to the configured quantum input form, transmitting the quantum input form to which polarization modulation is applied to a quantum measurement device, and authenticating the counterpart entity by checking whether the counterpart entity configures a quantum input form according to the shared authentication key using a measurement result and information about polarization modulation.
