Quantum Cryptography Put To Work For Electric Grid Security

"The simulator provides a mechanism for proving technology in real-world scenarios," said Tim Yardley, assistant director of test bed services. "We're not just using perfect or simulated data, so the results demonstrate true feasibility."

The power simulation was running a well-known power-bus model that was perturbed by introducing faults, which drove the analog inputs on the connected hardware PMU. The PMU then communicated via the standard protocol to the quantum cryptography equipment, which handled the key generation, communication and encryption/decryption of the connection traversing 25 kilometers of fiber. A phasor data concentrator then collected and visualized the data.

"This demonstration represents not only a realistic power model, but also leveraged hardware, software and standard communication protocols that are already widely deployed in the energy sector," said William H. Sanders, the Donald Biggar Willett Professor of Engineering at UIUC and principal investigator for TCIPG. "The success of the demonstration emphasizes the power of the TCIPG cyber-physical test bed and the strength of the quantum cryptography technology developed by Los Alamos."

The Los Alamos team submitted 23 U.S. and foreign patent applications for the inventions that make quantum-secured communications possible. The Los Alamos Technology Transfer Division has already received two licensing inquiries from companies in the electric grid control sector, and the office plans an industry workshop for early 2013 when the team's patents will be made available for licensing.

The Los Alamos team is seeking funding to develop a next-generation QKarD using integrated electro-photonics methods, which would be even smaller, more highly integrated, and open the door to a manufacturing process that would result in much lower unit costs.
