Abstract
According to one embodiment, a quantum key delivery service platform includes a plurality of quantum key delivery devices and a management server. The server monitors a storage amount of the encryption keys in the plurality of quantum key delivery devices, records a consumption record of the encryption keys for each of the plurality of cryptographic communication devices, predicts a consumption amount of the encryption keys based on the consumption record of the encryption keys, and detects a sign of shortage of the encryption keys based on the storage amount of the encryption keys and a prediction result of the consumption amount of the cryptographic keys.
