This project aims to develop a cloud datastore service based on secret sharing.
Cloud datastore services are essential for accessing your data from anywhere. However, they still carry risks of data leakage, as cloud services occasionally become targets of malicious attackers, and of data loss, since the hardware of each cloud service occasionally breaks down. To solve this problem, we've developed a cloud datastore service that employs a brand-new secret sharing scheme to distribute your data across several cloud services and physical locations around the world.
Our secret sharing scheme ensures that attackers who crack only some cloud services cannot reveal your data, and your data will not be lost even if some data centers are damaged, since your data are stored around the world.

- Shamir's secret sharing based key-value datastore
- Simple key-value datastore (to compare performance)
