Startup Gridcom uses photons and quantum physics for smart grid security


Cyber security has emerged as something that almost all power grid companies worry about and invest in, and entrepreneurs and startups are innovating to deliver new types of security solutions for the power grid. For example, an under the radar company called GridCOM Technologies tells us it’s developing a new tool based on quantum physics that could protect the grid from such digital security attacks.

Founded only last year, GridCOM’s technology uses something called quantum cryptography to generate codes using photons (tiny packets of light) that shield communications among a network of electronic equipment from the computers that control power transmission to smart meters. Quantum cryptography uses physics (instead of math like conventional encryption does) to secure cyber communications.

GridGridCOM’s approach is quite different from the conventional mathematically-based encryption methods traditional used to protect communications over the Internet, said Duncan Earl, co-founder and CTO of GridCOM and a former researcher…
