Abstract
A physically unclonable function (PUF) includes a plurality of PUF elements to generate an N-bit PUF signature. For each bit in the N-bit PUF signature, a PUF group of K number of individual PUF elements indicating a single-bit PUF value is used to generate a group bit. The group bits are more repeatable than the individual PUF elements. The value K may be selected such that (K+1)/2 is an odd number.
