ROBUSTNESS, RELIABILITY AND SECURITY OF BIOMETRIC KEY DISTILLATION IN THE INFORMATION THEORETICAL SETTING

摘要

In this contribution we model the security, robustness, and reliability of biometric key distillation schemes. Dodis et al. [DRS04] introduced fuzzy extractors. Theirrnmain motivation is that a fuzzy extractor can be used to construct a biometric key distillation scheme which is secure and robust wrt all distributions selected from a large class of reliable distributions (each of which describes biometric templates used for reference information, measured biometric templates, and adverserial side information). In this contribution we use our model to make this universal property explicit.
