Penn State researchers have designed a way to make encrypted keys harder to crack. They used graphene ‘ a layer of carbon one atom thick ‘ to develop a novel low-power, scalable, reconfigurable hardware security device. The device, called a physically unclonable function (PUF), is the first demonstration of a graphene-based PUF, according to the researchers. Further research can open pathways for its use in flexible and printable electronics, household devices and more. With these features, as well as the capacity to operate across a wide range of temperatures, it could be used in a variety of applications.
