A multiple-control fuzzy vault
Boles, Wageeh, Boyd, Colin, & Hirschbichler, Marianne (2008) A multiple-control fuzzy vault. In Korba, L, Marsh, S, & Safavi-Naini, R (Eds.) Proceedings of Sixth Annual Conference on Privacy, Security and Trust, 2008, 1-3 October, 2008, New Brunswick, Canada.
We introduce multiple-control fuzzy vaults allowing generalised threshold, compartmented and multilevel access structure. The presented schemes enable many useful applications employing multiple users and/or multiple locking sets. Introducing the original single control fuzzy vault of Juels and Sudan we identify several similarities and differences between their vault and secret sharing schemes which influence how best to obtain working generalisations. We design multiple-control fuzzy vaults suggesting applications using biometric credentials as locking and unlocking values. Furthermore we assess the security of our obtained generalisations for insider/ outsider attacks and examine the access-complexity for legitimate vault owners.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
