Recombination of Physical Unclonable Functions
Meng-Day Yu, Srinivas Devadas · DSpace@MIT (Massachusetts Institute of Technology) · 2010
A new Physical Unclonable Function (PUF) construction is described, by treating silicon unique features extracted from PUF circuits as “genetic material” unique to each silicon, and recombining this chip-unique material in a way to obtain a combination of advantages not possible with the original PUF circuits, including altering PUF output statistics to better suit PUF-based key generation and authentication.
