Secret Sharing

Summary

The aim of this project is to develop a secret sharing based cloud datastore service.

Cloud datastore services have been essential to access your data from anywhere. However, they still have risks of data leakage since each cloud service occasionally becomes a target from malicious attackers and data loss since hardwares of each cloud service occasionally are broken. To solve this problem, we've developed a cloud datastore service which employs a brand-new secret sharing scheme to distribute your data over several cloud servicers and several actual places around the world.

Our secret sharing scheme ensures no attackers who crack only some cloud servicers can reveal your data, and your data will not be lost even if some data centers get damages since your data are stored around the world.
