Nano-encryption may soon foil the best hackers

Researchers at the Center for Quantum Information and Quantum Control at the University of Toronto have discovered a method of nano-scale encryption (nano-encryption) to thwart even the most sophisticated of hackers.

Professor Hoi-Kwong Lo, along with Professor Marcos Curty and researcher Bing Qi, were researching ways around quantum cryptography’s weak spot: light signals sending encrypted data can be intercepted and manipulated by a hacker before they reach the photon detectors. Essentially, the hacker can change the light signals seen by the person or computer on the other end. It’s called quantum hacking.

Lo & Co’s solution, Measurement Device Independent QKD (quantum key distribution), allows the sender and receiver to measure and compare their results, which will reveal if a hacker has manipulated the data. Lo and his team of researchers expect a prototype device to be ready in five years.

Governments, particularly spy agencies and diplomatic services, will be interested in this technology, but, let us hope that this sort of encryption will make its way into the hands of internet users to prevent Orwellian spying from their own governments. People should be able to communicate securely without Big Brother hacking into emails, as we have seen with the NSA.
