Document Type and Number:
WIPO Patent Application WO/2024/038568
Kind Code:
A1
Abstract:
A physical encryption device according to the present disclosure comprises: a probabilistic shaping encoding unit (101) that executes probabilistic shaping on a plurality of bits inputted from the outside; an error correction encoding unit (102) that executes error correction encoding on error correction information bits sent from the probabilistic shaping encoding unit (101); a provisional symbol generation unit (103) that generates a provisional symbol from a bit string composed of the error correction information bits and error correction redundant bits; an encryption bit string generation unit (111) that generates an encryption bit string on the basis of a shared key; an encryption matrix generation unit (112) that determines an encryption matrix on the basis of at least a part of the encryption bit string; and an encryption symbol generation unit (104) that generates an encryption symbol from the provisional symbol by using the encryption matrix.
