Abstract

Provided is an electronic device and a method thereof for repairing response bits of a physical unclonable function of an electronic device, said physical unclonable function outputting said response bits and additional output bits. The method includes generating a PUF response from said response bits (S), detecting an error in the PUF response (S), determining erroneous response bits of the PUF response (S), determining a match (S) between each determined erroneous response bit and a selected additional output bit such that replacing the erroneous response bits by the matching additional output bits corrects the error in the PUF response, storing said determined match in a repair list (S), and replacing (S) in the PUF response said erroneous response bits with the matching additional output bits in the repair list. Other embodiments disclosed.
