KEY OFFSITE STORAGE-BASED DATA ENCRYPTION STORAGE SYSTEM AND METHOD

摘要

The present disclosure provides an encrypted data storage system and method based on offsite key storage, comprising a key control center, an offsite key storage system, and a data encryption / decryption storage system. The offsite key storage system comprises a first key control device, a key storage device, and a first quantum key distribution device. The data encryption / decryption storage system comprises a second key control device, a data encryption / decryption storage device, and a second quantum key distribution device. The first quantum key distribution device is in quantum communication connection with the second quantum key distribution device. The first key control device is communicatively connected with the key storage device and the first quantum key distribution device, respectively. The second key control device is communicatively connected with the data encryption / decryption storage device and the second quantum key distribution device, respectively. The present disclosure is capable of securely and reliably setting the offsite key storage system and the data encryption / decryption storage system separately at any distance, so that encryption / decryption keys are stored separately and securely from data.
