With the upsurge of data storage migration to public cloud environments the need to ensure data confidentiality and integrity becomes increasingly critical. Fibre optic, encryption and post-quantum encryption are various approaches to data protection but these have limitations.
Researchers at The University of Queensland have developed an approach to verify the physical security of fibre optic cabling using quantum technology. The cable can be continuously monitored and, if compromised, data transmission halted.
Quantum Link Verification relies on well-documented, tested and verified scientific concepts and can be demonstrated using off-the-shelf hardware. The next step is a lab-based demonstration to show the proof of concept for integration within classical communication networks.
In the longer term, the technology can be applied to emerging communications links, for example free space optical links using LEO satellite networks.
Key features:
- Verify fibre optic communications links using ‘unspoofable’ quantum technology
- Backwards compatible with fibre infrastructure
- Uses commercial off-the-shelf components.
