  • Silicon physical unclonable functions (PUFs) produce a sequence of response bits from chip-unique manufacturing variations. Since the response bits are physically derived, there is noise present. To generate bit-exact cryptographic keys, error correction algorithms are used. The error correction is typically split into small processing blocks to reduce implementation complexity. The reliability of PUF responses varies from bit to bit, but there has been very little work so far that… CONTINUE READING
