Berk Sunar, associate professor of electrical and computer engineering at Worcester Polytechnic institute (WPI), is developing ways to use physical features of high-tech devices like computer chips and CDs to create cryptographic fingerprints that can detect tampering or prevent unauthorized copying. These fingerprints take advantage of nano-scale variations in the physical characteristics of the devices, which Sunar calls "hardware primitives.
