Abstract:
Approaches for using a physically unclonable function (PUF) are described. A selector map is used to indicate stable and unstable bits in a PUF value that is generated by a PUF circuit. The stable bits of the PUF value generated by the PUF circuit may be selected for use by an application, and the unstable bits ignored.
