Quantum Cryptography Secures the Electrical Grid

By Cabe Atwell – The variability of renewable sources are mainly caused by weather fluctuation, but can also be complicated by their long-distance location from heavily populated areas. This uncertainty is handled by grid management systems that properly allocate available renewable energy sources when available, but also quickly switches the energy supply to conventional reserves when a deficit occurs; a similar method is employed for energy excesses. To safeguard the grid’s management system, scientists hope to employ the latest encrypted data security measure — quantum cryptography.

A team of researchers at the Los Alamos National Laboratory has successfully demonstrated the use of the new technology to safeguard data transmission. Quantum cryptography exploits the use of physics, rather than mathematical methods, to safely transmit data over long distances. more> http://tinyurl.com/ckp3o3x
