Quantum Bridge's Symmetric-Key Distribution System supports crypto-agile key management, including DSKE. In the demonstrated Toshiba architecture, DSKE connects distant QKD networks through conventional communications using pre-shared random data and distributed security hubs; the QKD and international DSKE portions have different physical and trust requirements.

The official capability material supports the named Quantum-safe communications security offering and the bounded operational description prepared for reviewer consideration.
Quantum Bridge and Toshiba demonstrated linked Toronto and Cambridge quantum-key networks using DSKE for the international segment. DSKE distributes symmetric keys using pre-shared random data and multiple security hubs over conventional communications. The experiment used draft ETSI GS QKD 020 interoperability interfaces; it did not send quantum states directly across the Atlantic.
