Abstract
A system for providing security in a computer system is provided. The system includes a physical unclonable function (PUF) device and one or more logic circuits. At startup of the computer system, the logic circuits call the PUF device a preset plurality of times with an identical input value to generate a plurality of PUF values that are candidate identifiers of an integrated circuit. The logic circuits apply a hash function to the candidate identifiers to produce respective hash values. The logic circuits also access a reference hash value from a non-volatile memory and verify all of the respective hash values using the reference hash value. The logic circuits further enable the computer system to operate in a first mode or a second mode based on the verification results.
