Mathematics of Secure Key Extraction from Noisy Data
Abstract: Recently, there is a lot of interest in key extraction from noisy data. This
method plays an important in role in privacy preserving biometric authentication
and in the extraction of secure unclonable keys for ICs. Extracting keys from
noisy measurements is highly non-trivial. In this lecture we will explain the basic
ideas behind the helper data algorithm or Fuzzy extractor that has been
developed for this purpose. The ideas will be illustrated with some simple
mathematical examples as well as examples from real life.
