Abstract
A data processing device includes a Physical Unclonable Function value source which is set up to provide a reference Physical Unclonable Function value and a plurality of subsequent Physical Unclonable Function values, the reference Physical Unclonable Function value and each subsequent Physical Unclonable Function value having a multiplicity of binary components, a determination device which is set up to determine a set of components, the value of which is identical in the plurality of subsequent Physical Unclonable Function values, and a Physical Unclonable Function reconstruction device which is set up to reconstruct the reference Physical Unclonable Function value from the subsequent Physical Unclonable Function values assuming that the values of the determined components in the subsequent Physical Unclonable Function value match the values of the determined components in the reference Physical Unclonable Function value.
