A solar-powered airplane finished crossing the United States on Saturday, landing in New York City after flying over the Statue of Liberty during its historic bid to circle the globe, the project team said. The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived at New York's John F. Kennedy International Airport at about 4 a.m. local time after it took off about five hours beforehand at Lehigh Valley International Airport in Pennsylvania, the team reported on the airplane's website. Such a pleasure to land in New York! For the 14th time we celebrate sustainability," said the project's co-founder Andre Borschberg on Twitter after flying over the city and the Statue of Liberty during the 14th leg of the trip around the globe. The Swiss team flying the aircraft in a campaign to build support for clean energy technologies hopes eventually to complete its circumnavigation in Abu Dhabi, where the journey began in March 2015. The solar cr...
The tiny identity tags are essentially tiny imperfections in the building blocks of matter, making them virtually impossible to clone. They could be used as the basis of a robust system for authenticating hardware and software. Details of the work are published in the journal Scientific Reports. The researchers from the UK universities of Lancaster and Manchester built tiny, layered metallic structures in the lab and incorporated "design flaws" that were unique to the item.
"And the interesting thing is that you can't clone them. To clone them, you'd effectively have to measure atom-by-atom. You just can't do it." The fingerprint structures were demonstrated at the nano-scale where the laws of quantum mechanics take over from the ones that predominate at larger scales.
But the researchers say it is a proof of principle which could be integrated into existing chip manufacturing processes. "These could be used to authenticate any electronic equipment and be 100% secure," said Dr Roberts. "Having one of these devices in each and every piece of electronic equipment, you could challenge that electronic device and see what it outputs in order to identify it."
"If you imagine self-driving cars communicating with a fake server, that could have dramatic consequences." The technology is already being commercialised through a spin-out company Quantum Base.
