Document Type and Number:
WIPO Patent Application WO/2022/163108
Kind Code:
A1
Abstract:
Provided is a quantum key delivery service platform that can adaptively manage a cryptographic key. According to an embodiment, the quantum key delivery service platform comprises a plurality of quantum key delivery devices and a management server. Each of the plurality of quantum key delivery devices transmits/receives cryptographic key information to/from another quantum key delivery device, and on the basis of the cryptographic key information, generates a cryptographic key to be shared with the other quantum key delivery device. The management server: monitors the accumulation amount of cryptographic keys accumulated by each of a plurality of cipher communication devices in the plurality of quantum key delivery devices; records a consumption record for the cryptographic keys of each of the plurality of cipher communication devices; predicts a consumption amount for the cryptographic keys of each of the plurality of cipher communication devices, on the basis of the cryptographic key consumption records; and detects, on the basis of the cryptographic key accumulation amounts and the prediction results for the cryptographic key consumption amounts, a sign of insufficient cryptographic keys that could occur for cipher communications between the plurality of cipher communication devices.
