Using Convolutional Codes for Key Extraction in Physical Unclonable Functions | | Sven Müelich
; Martin Bossert
; | | Date: |
5 Apr 2017 | | 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. | | Source: | arXiv, 1704.1306 | | Services: | Forum | Review | PDF | Favorites | |
