CREDIT Jennifer McCann,Penn State Abstract: As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys ...

Graphene physically unclonable function Graphene transistors have been used to create a physically unclonable function (a PUF) – one of the key building blocks of high-end on-chip security. PUFs create numbers from the fine-grained randomness found in in an individual IC, due to doping and manufacturing variations, for example. In this case, variations in the carrier transport of graphene transistors was used, which follow Gaussian random distributions, according to Penn State University, where the PUF was made. The team first fabricated nearly 2,000 graphene transistors, intended to be ide...

Graphene key for novel hardware security As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, Penn State researchers have designed a way to make the encrypted keys harder to crack. Led by Saptarshi Das, assistant professor of engineering science and mechanics, the researchers used graphene — ...

Researchers design a graphene-based encrypted key for novel hardware security Penn State researchers have designed a graphene-based way to make encrypted keys harder to crack, in an attempt to protect data in an age where more and more private data is stored and shared digitally. Current silicon technology exploits microscopic differences between computing components to create secure keys, but the team explains that artificial intelligence (AI) techniques can be used to predict these keys and gain access to data.
