Abstract: An integrated circuit substrate of an aspect includes a plurality of exposed electrical contacts. The integrated circuit substrate also includes an inaccessible set of Physically Unclonable Function (PUF) cells to generate an inaccessible set of PUF bits that are not accessible through the exposed electrical contacts. The integrated circuit substrate also includes an accessible set of PUF cells to generate an accessible set of PUF bits that are accessible through the exposed electrical contacts. Other apparatus, methods, and systems are also disclosed.
