With the advent of the Internet of Things, lightweight devices necessitate secure and cost-efficient key storage. Since traditional secure storage is expensive, the valuable entropy could originate fr...
A fuzzy extractor is a security primitive that allows
for reproducible extraction of an almost uniform key from a noisy
non-uniform source. We analyze a fuzzy extractor scheme that
uses universal h...

We consider the problem of building robust fuzzy extractors, which allow two parties holding
similar random variablesW, W0 to agree on a secret key R in the presence of an active adversary.
