Abstract:
A key enrollment method of a physically unclonable function (PUF) circuit including a plurality of PUF cells includes receiving a first level key from PUF cells, performing bit encoding on the first level key using a bit coding table based on Hamming weights of a plurality of bits in the first level key to generate a second level key, storing first helper data associated with the second level key in a non-volatile memory, performing block encoding on the second level key using an error correction code to generate a third level key, and storing second helper data associated with the third level key in the non-volatile memory.

Claim (Index 5):
The method of  claim 4 , wherein if the corresponding one of the plurality of second bits is the first logic value, corresponding one of the plurality of first key values is the same as corresponding one of the plurality of mask values,\n if the corresponding one of the plurality of second bits is the second logic value, corresponding one of the plurality of first key values is a value to which the corresponding one of the plurality of mask values is inverted.
