Quantum key distribution as well as emerging techniques that harness temporal cloaking and optomechanical crystals vie for securing optical communications.

HANK HOGAN, CONTRIBUTING EDITOR, [email protected]

Much of the world’s communications travel by light. So, data carried on photons moving through free space or over fiber must be made as secure as possible. Quantum key distribution helps do that. Also, security improvements via temporal cloaking and optomechanical crystals are on the horizon. However, even when these and other new methods are deployed, there will still be gaps in the data armor. For that reason, a layered defense is best, such as the use of multiple levels of encryption, said Gregory Kanter, CEO of Evanston, Ill.-based NuCrypt LLC. The company was founded to...Read full article
