The ultimate defense against hackers may be just a few atoms thick

ScienceDaily.com: Nanotechnology News - Wed, 11/29/2017 - 18:04
The next generation of electronic hardware security may be at hand as researchers introduce a new class of unclonable cybersecurity security primitives made of a low-cost nanomaterial with the highest possible level of structural randomness. Randomness is highly desirable for constructing the security primitives that encrypt and thereby secure computer hardware and data physically, rather than by programming.
