A data-sharing scheme utilizing an encryption manager shows the way towards low-cost, flexible and secure cloud storage services
Wider adoption of cloud storage services by organizations has been hindered by security and privacy issues. A consequence of storing data on the cloud is that, by its very nature, the storage infrastructure is not owned by the same organization that owns the data. In addition, the data of one user is stored along with that of many others. Traditional schemes for ensuring security can only protect data privacy by sacrificing convenient operations such as searching and sharing.
Now, Shu Qin Ren and his colleague Khin Mi Mi Aung at the A*STAR Data Storage Institute in Singapore have devised a scheme that would not only allow organizations to store data on the cloud without loss of privacy but also permit searching and sharing of the data1. The system is able to preserve the benefit of the cloud’s specialized low-cost storage infrastructure while overcoming its current privacy and flexibility limitations. “The scheme may potentially push forward the wider adoption of cloud storage usage for organizations,” says Ren.
The solution proposed by the researchers involves a central ‘key manager’, who specifically manages data authentication and access authorization. In their scheme, data stored on the cloud is encrypted by its owner and hence is indecipherable to anyone else — including the cloud storage provider. A secret key required to unlock the encryption is generated and kept by the owner, who also determines an access policy for other users. This policy is implemented by the key manager, who generates a second access key, which is then passed back to the owner. Next, the owner wraps the original encryption key in this second layer of protection. The key manager is then able to pass on the second ‘public’ key to authorized third parties to allow them to access the data.
