Abstract
A reception device comprises: a quantum communication unit that receives key information, including information from which a shift key is derived; a random number generation unit that generates a random number in which a portion of the key information is compressed on the basis of a characteristic value of noise in the reception of the key information; and an error correction unit that performs information reconciliation on the basis of the random number.
Claims10
A reception device comprising:
- at least one memory storing instructions and
- at least one processor configured to execute the instructions to:
- receive key information including information to be a basis of a shift key;
- generate a random number obtained by compressing a part of the key information based on a characteristic value of noise in reception of the key information;
- and
- perform information reconciliation based on the random number.

An information reconciliation method comprising:
- receiving key information including information to be a basis of a shift key;
- generating a random number obtained by compressing a part of the key information based on a characteristic value of noise in reception of the key information;
- and
- performing information reconciliation based on the random number.
A non-transitory computer-readable medium storing a program for causing a computer to execute processing of:
- receiving key information including information to be a basis of a shift key;
- generating a random number obtained by compressing a part of the key information based on a characteristic value of noise in reception of the key information;
- and
- performing information reconciliation based on the random number.
