Researchers at Ohio State University are introducing chaos into computer chips to develop digital fingerprints that may be unique enough to foil even the most sophisticated hackers.
The new solution makes use of an emerging technology called physically unclonable functions, or PUFs, to take advantage of tiny manufacturing variations found in each computer chip. These slight variations – sometimes seen only at the atomic level – can create unique sequences of 0s and 1s that PUF researchers in the field call “secrets.”
Currently PUFs have a great but limited number of secrets, making them vulnerable to hackers that have the time and technology to break them. However, the Ohio State team has “found a way to produce an uncountably large number of secrets to use that will make it next to impossible for hackers to figure them out, even if they had direct access to the computer chip,” Daniel Gauthier, senior author of the study and physics professo

COLUMBUS, Ohio Some might say candy can make you feel better by elevating your mood in certain situations, but scientists are putting it to an even more impactful use.
Researchers at Ohio State University are proposing that using hard candy to look for the loss of taste and smell in populations who are at risk of getting exposed to COVID-19 may help find probable cases of the virus in otherwise asymptomatic people.
The OSU research team got more than $300,000 to fund their study from the National Institutes of Health to figure out easier ways to identify people who have potentially contracted COVID-19.
"The mutations in the Columbus strain are likely to make the virus more infectious, making it easier for the virus to pass from person to person," Ohio State University said in a statement.
