CORRECTING PHYSICAL UNCLONABLE FUNCTION ERRORS BASED ON SHORT INTEGERS SOLUTIONS TO LATTICE PROBLEMS

Abstract:

Physical unclonable functions (PUFs) are described. The PUFs utilize intrinsic information to determine the confidence level of comparison values. The information about confidence levels may be used to simplify the process of recovering the PUF secret. Since the information about confidence levels may be intrinsic, and not know outside the PUF, the PUF may be secure.
