Abstract:
A method for reconstructing a physically uncloneable function (PUF) A for use in an electronic device is provided. The method includes generating a potentially erroneous PUF At and performing a preliminary correction of the potentially erroneous PUF At by means of a stored correction vector Deltat-1, to obtain a preliminarily corrected PUF Bt. The PUF A is reconstructed from the preliminarily corrected PUF Bt by means of an error correction algorithm. A corresponding apparatus is also provided.
