| Abstract: The various technologies presented herein relate to enabling a value
generated based upon a physical unclonable function (PUF) response to be
available as needed, while also preventing exposure of the PUF to a
malicious entity. A masked PUF response can be generated based upon
applying a function to a combination of the PUF response and a data file
(e.g., a bitstream), and the masked PUF response is forwarded to a
requesting entity, rather than the PUF response. Hence, the PUF is masked
from any entity requiring access to the PUF. The PUF can be located in a
FPGA, wherein the data file is a bitstream pertinent to one or more
configurable logic blocks included in the FPGA. A first masked PUF
response generated with a first data file can have a different value to a
second masked PUF response generated with a second data file. |
