Recently, Guodun Quantum has proposed a quantum secure fault-tolerant distributed cloud storage system in conjunction with the research teams of Micro-aware Quantum, Yiketeng, Tsinghua University, Superfluid Information, SinoScience Quantum, and Shanghai Jiaotong University, which further promotes the application of Quantum key Distribution (QKD) in cloud storage through the innovative research and development of key performances such as cloud storage security, fault-tolerant backup and storage space. The results are published in AIP Advances, an authoritative international academic journal, in the form of "editorial recommendation".

In the digital age, cloud data storage has increasingly become the first choice for enterprises and individuals. However, under the advantages of convenient and scalable cloud storage, how to ensure the security and autonomous control of data has also become an urgent problem to be solved. QKD is the first practical quantum information technology. Based on the basic principles of quantum mechanics, it can realize the secure communication of information theory. It has been gradually applied in government affairs, electric power, communications and other fields. It also provides a new idea for the data security of cloud storage.

The proposed quantum secure fault-tolerant distributed cloud storage system encrypts the data to be stored through QKD and symmetric encryption technology, and ensures the security and isolation of the whole process of data uploading to the server and transmission from the server to the cloud storage node. In addition, the system uses erasure code technology for distributed storage of data, which improves data fault tolerance and significantly reduces data storage space requirements. Experiments show that compared with the previous quantum security cloud system, the new cloud storage system not only realizes quantum security, but also provides higher flexibility and cost-effectiveness. As a fusion practice of quantum physics and mature encryption and storage technology, the system has engineering and technical feasibility.

The application of QKD in the field of cloud storage is an international universal exploration of quantum technology landing scene. Previously, the National Institute of Information and Communication Technology of Japan has been seeking the possibility of quantum security cloud systems to analyze and protect human genome data. ThinkQuantum Srl, an Italian quantum communications company, and fragmentiX, an Austrian network security company, have also proposed quantum secure cloud data storage solutions to promote the application of QKD in storage and communications.

According to the researchers of Guodun Quantum, ensuring the data security of cloud storage is not only a simple way to encrypt the data, but also to further consider the disaster recovery and anti-loss capability and use cost of the storage system. The proposed quantum secure fault-tolerant distributed cloud storage system not only uses quantum technology to achieve secure data transmission, but also further enriches quantum security services such as performance optimization in data storage and processing. The next step is to push this scheme to the actual application scenario, and further promote the transformation of scientific research achievements to industrial applications.
