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 4):
The method of  claim 1 , wherein if the hamming weight is even, a corresponding one of the plurality of second bits is a first logic value, and\n if hamming weight is odd, the corresponding one of the plurality of second bits is a second logic value.
