Encrypted data storage system and method based on remote storage of key

Abstract

The invention discloses an encrypted data storage system and method based on key remote storage, including a key control center, a key remote storage system, and a data encryption and decryption storage system. The key remote storage system includes a first key control device, The key storage device and the first quantum key distribution device, the data encryption and decryption storage system includes the second key control device, the data encryption and decryption storage device and the second quantum key distribution device, the first quantum key distribution device and the second The quantum key distribution device is connected by quantum communication, the first key control device is respectively connected with the key storage device and the first quantum key distribution device, and the second key control device is respectively connected with the data encryption and decryption storage device and the second quantum encryption device. The key distribution device is connected by communication; the present invention can safely and reliably set the remote key storage system and the data encryption and decryption storage system to be separated at any distance, so as to realize the separate safe storage of the encryption and decryption key and the data.

Description

technical field [0001] The invention relates to the fields of information transmission and storage and information security, in particular to an encrypted data storage system and method based on key remote storage. Background technique [0002] Information is an important strategic resource for social development. From national security to personal privacy protection, all levels are related to information security. Among them, under the promotion of digital technology, the storage and flow transmission of information into data are two crucial links in the process of information flow and use. In these two links, information and data are safe from eavesdropping and theft. Therefore, how to protect the security of information and data is an eternally important topic. [0003] In the field of data storage, with the accumulation of current data volume and the substantial expansion of data applications, in addition to personal computers, enterprise servers and storage centers, th...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an encrypted data storage system and method based on remote storage of keys for the above-mentioned deficiencies in the prior art. Unable to solve the problem of how to securely separate and store the encryption key and ciphertext data, the present invention can solve the problem of key security in the process of structured and unstructured data storage, database storage, data backup, cloud storage and cloud computing Storage and ciphertext data encryption and decryption storage problems, because the amount of encrypted keys can be many times smaller than the stored data, storing and managing the key store (key storage device) in different places is much less difficult than strictly managing data, so it can be effectively solved Security issues in the storage and computing process of various structured and unstructured data storage and databases, cloud storage and cloud computing
