Generic Constructions of Biometric Identity Based Encryption Systems
Résumé
In this paper, we present a novel framework for the
generic construction of biometric Identity Based Encryption (IBE)
schemes, which do not require bilinear pairings and result in more
efficient schemes than existing fuzzy IBE systems implemented for
biometric identities. Also, we analyze the security properties that are
specific to biometric IBE namely anonymity and identity privacy.
Considering these notions, we present generic constructions for
biometric IBE and ID-KEM based on weakly secure anonymous IBE schemes,
error correcting codes and generic conversion schemes. Finally, we
describe concrete applications of our framework and compare them to the
existing fuzzy IBE systems in terms of time complexity.
