Dutch researchers have developed technology to debit cards, credit cards, identity cards and digital door locks of cars to protect. Although the basis is based on the quantum mechanics, the technology is inexpensive and easy to deploy.
According to the researchers of the MESA+institute of the University of Twente and the TU/e are passes, their method is impossible to crack and bypass the security via copying or duplicating keys would not be able to. The scientists have their method to Quantum-Secure Authentication called. Despite the name, is for the protection only a layer of white paint in combination with a laser, the image sensor and the imaging chip is necessary. The laser for reading of information, similar to an optical drive, and the imaging chip is used for projection, as a beamer.
The protect only of a layer of white paint containing millions of nanoparticles. “If you are a light particle of the paint in the send will, if in a pinball machine, between the nanoparticles ‘doorstuiteren “to escape”, describes the University of Twente. The intention is that banks and other organisations a unique pattern of light particles on passes, go to project, after which a reading device, the resulting pattern of escaping light particles registers for authentication.
In theory, it might allow an attacker to this question and answer method can mimic this by starting stipjespatroon analyze, but the security of the researchers is that a pattern is used that less photons than there lichtstipjes. This allows an attacker to never find out what pattern the paint effect and the resultant outgoing pattern, so it is not recreated.
The method is based on one of the most famous experiments in physics: the units of measurement. This produces an interference pattern when only a single photon through two slits at the same time. The light particle seems to be with himself to interfere, and thus in multiple places, which is the basis of the quantum mechanics. “The bank can even with only one photon, the answer check,” concludes the University of Twente.
The research with the title ” Quantum-Secure Authentication of a Physical Unclonable Key is Tuesday, published in the scientific journal of Optics of The Optical Society.
