Global Technolgy Briefing

Briefings Researchers at Ohio State University have found a way to use chaos to create digital fingerprints for electronic devices that may be unique enough to foil even the most sophisticated hackers. Just how unique are these fingerprints? The researchers believe it would take longer than the lifetime of the universe to test for every possible combination available.The study, recently published online in the journal IEEE Access, involves an emerging technology called physically unclonable functions, or PUFs, that are built into computer chips.These new PUFs could potentially be used to create secure ID cards, to track goods in supply chains and as part of authentication applications, where it is vital to know that you’re not communicating with an impostor.
