Qasmat : technical overview

What is Qasmat?

Qasmat is a software solution for secure distributed cloud storage. It uses a Proactive Secret Sharing scheme to produces, given some data to protect, secret shares to distribute on various servers. This prevents single nodes of compromission: an eavesdropper that wants to learn your secret data would need to attack several storage servers.

The technical documentation of Qasmat, and instruction for installation can be found at

Qasmat is also quantum-ready. It can be deployed over a QKD network, resulting in even higher security guarantees, providing long-term security for data storage. Moreover, the data are contiunously re-encrypted, by updating and distributing new secret shares to the storage servers.
