Abstract
A device may include one or more sources such as circuit elements and electrical components that function as sources for physically unclonable function (PUF) data. PUF data may be acquired from the PUF sources and one or more error correction codes may be applied to the PUF data. The resulting PUF values may be used to generate information that may be used for device security operations such as encryption and tamper detection.
