Titel:
Hiding Secrecy Leakage in Leaky Helper Data 
Abstract:
PUFs provide cryptographic keys for embedded systems without dedicated secure memory. Practical PUF implementations often show a bias in the PUF responses, which leads to secrecy leakage in many key derivation constructions. However, previously proposed mitigation techniques remove the bias at the expense of discarding large numbers of PUF response bits. Instead of removing the bias from the input sequence, this work reduces the secrecy leakage through the helper data. We apply the concept of wi...    »
