Quantum Communication and Security

Because quantum bits, or qubits, are highly sensitive, they can act as secure carriers of information. The laws of quantum mechanics guarantee that it is impossible to eavesdrop or otherwise tamper with the qubits without changing them in a detectable way. By applying this unique quantum feature, ORNL researchers use quantum key distribution (QKD) and other quantum security applications to improve information security for data storage and distribution.

Practical Quantum Security for Grid Automation
— Conventional approaches to Quantum Key Distribution (QKD) are hampered by several problems:

Grid Security using Quantum Architectures and Resources
— The electric grid is becoming “smarter” through better use of information. With more information comes greater vulnerability and greater risk, not only to consumer information, but also to the security of the grid itself.

Secure Token Authentication via Secure Hashing
— Authentication through single-factor and current two factor methods is insecure. Pseudorandom number generators used in these methods are predictable in principle due to their inherent determinism. Unsecure seed lists can be retrieved from compromised servers, and hash functions can be reverse engineered.
