  • Patent number: 10958428
    Abstract: A device and method for quantum key distribution (QKD). The QKD center includes an authentication key sharing unit for sharing authentication keys with QKD client devices; a quantum key generation unit for generating a sifted key for each of the QKD client devices using a quantum state; an error correction unit for generating output bit strings by correcting errors of the sifted keys; and a bit string operation unit for calculating an encryption bit string by performing a cryptographic operation on the authentication keys, the distribution output bit strings and output bit strings received from the QKD client devices. The present invention improves security by preventing the QKD center from being aware of keys shared among users.

  • Patent number: 8802062
    Abstract: Disclosed herein is a pair of dry type patches for teeth whitening, having a patch for upper teeth and a patch for lower teeth, in which the patch for upper teeth has a shape different from the patch for lower teeth, and each patch has a controlled width and shape such that the contact area of each patch with gums is minimized. In the patch for upper teeth, a central portion covering right and left upper central incisors is widest. In the patch for lower teeth, either portion covering right and left lower canine teeth is widest. Since the dry type patches covers all the portions of the teeth while minimizing the contact area with gums, no or little irritation is caused and wearability is excellent.
