  • Publication number: 20240089124
    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.

  • Patent number: 9041859
    Abstract: An image sensor assembly includes: an image sensor; a support plate disposed on a back surface of the image sensor; a first frame which includes a first hole which is open allowing incident light onto the image sensor and is disposed on a front surface of the support plate to enclose at least a side edge of the image sensor; an optical filter disposed in the first hole to block a part of the incident light; a second frame which includes a second hole which is open to allow light to be incident onto the optical filter and is disposed in front of the first frame; a front plate which is disposed in front of the second hole to contact a front surface of at least a side edge of the second frame; and a vibrator which is combined with at least a side edge of the front plate.
