Center hyperedge (induced by source paper "using convolutional codes for key extraction in physical unclonable functions"):
  Abstract: Physical Unclonable Functions (PUFs) exploit variations in the manufacturing process to derive bit sequences from integrated circuits which can be used as secure cryptographic keys. Instead of storing the keys, they can be reproduced when needed. Since the reproduced sequences are not stable, error correction must be applied. Recently, convolutional codes were used for key reproduction. This work shows that using soft information at the input of the decoder and list decoding reduces the key error probability compared to results from the literature.
