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.
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.
