"Keep It Secret: Cloud Data Storage Security Approach Taps Quantum Physics"

A research team in China is using quantum physics, mature cryptography, and storage techniques to create a cost-effective cloud storage solution. Shamir's Secret Sharing (SSS) is a known key distribution algorithm involving distributing private information to a group so that the secret can only be revealed when a majority pools their knowledge. Combining Quantum Key Distribution (QKD) and the SSS algorithm is common for secure storage at the highest security level. However, the most secure solutions tend to be costly, especially regarding cloud storage space requirements. The team presented their method in AIP Advances. It uses quantum random numbers as encryption keys, disperses the keys using the SSS algorithm, uses erasure coding within ciphertext, and securely transmits the data to distributed clouds via QKD-protected networks. This article continues to discuss the cloud data storage security approach.
