Title:
PHYSICAL ENCRYPTION DEVICE, PHYSICAL ENCRYPTION METHOD, PHYSICAL DECRYPTION DEVICE, AND PHYSICAL DECRYPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/038633
Kind Code:
A1
Abstract:
A physical encryption device according to the present disclosed technology comprises: a probabilistic shaping encoding unit (101) that implements a probabilistic shaping with respect to multiple externally inputted bits; an error correction encoding unit (102) that performs an error correction encoding with respect to error correction information bits sent from the probabilistic shaping encoding unit (101); a provisional symbol generating unit (103) that generates a provisional symbol from a bit sequence consisting of the error correction information bits and error correction redundant bits; an encrypted bit sequence generating unit (111) that generates an encrypted bit sequence on the basis of a shared key; an encrypted matrix generating unit (112) that determines an encrypted matrix on the basis of at least a portion of the encrypted bit sequence; an encrypted symbol generating unit (104) that uses the encrypted matrix to generate an encrypted symbol from the provisional symbol; an encrypted known-symbol generating unit (106) that encrypts a known symbol into an encrypted known-symbol; and an encrypted symbol multiplexing unit (107) that multiplexes the encrypted symbol with the encrypted known-symbol.
