Use Cases

The QKD networked deployed as part of QCI-CAT serves as testbed for three use cases: the backup of keys of a Hardware Security Module, secure video conferencing, secure exchange of govermental and medical data.

HSM Backup

In the Hardware Security Module (HSM) backup use case, keys stored in a HSM are transferred using a QKD-protected network to a backup HSM.

Medical Use Case

In the medical use case, medical data is exchanged securely between the Medical University in Graz and collaborators in Vienna.

Secure Video Links

This use cases implements a federated video conferencing solution which combines key material from both QKD links and post-quantum secure key exchange to protect individual sessions.

Governmental Use Case

This use case implements a secret sharing-based storage solution that is protected with quantum-resistant communication between Austrian ministries.
