Quantum cryptography, quantum cryptogram communication rate calculation system and quantum cryptogram communication fee calculation method

摘要

Problem: the unit price of the app key transmitted by the cipher communication using the cipher key generated by the quantum cryptographic communication system is changed to a more appropriate value depending on the usage state of the app key.The quantum cryptographic device of the embodiment comprises a totaling section, a computing section and a display section. The totalization section collects information of an application key transmitted and received using a quantum cryptographic key, and outputs the result of an application key information aggregation. The calculating unit calculates the unit price of the above described key key based on the result of the above described key information. The display unit displays display information including the unit price of the above described key.Selection diagram
