Robust Fuzzy Extractors and Authenticated Key Agreement from Close SecretsExtractors and Authenticated Key Agreement • April 21st, 2024
Abstract. Consider two parties holding correlated random variables W and W', respectively, that are within distance t of each other in some metric space. These parties wish to agree on a uniformly distributed secret key R by sending a single message over an insecure channel con- trolled by an all-powerful adversary. We consider both the keyless case, where the parties share no additional secret information, and the keyed case, where the parties share a long-term secret SK that they can use to generate a sequence of session keys Rj using multiple pairs (Wj, Wj') . The former has applications to, e.g., biometric authentication, while the latter arises in, e.g., the bounded storage model with errors.
