Title: 
the construction of two new fuzzy identity-based encryption
(IBE) schemes in the random oracle model

Abstract:
In this talk we discuss the construction of two new fuzzy identity-based encryption
(IBE) schemes in the random oracle model.
Fuzzy identity-based is a new notion that can be used for biometric authentication
and attribute based authentication schemes.
We show that not only do our schemes
provide public parameters whose size is independent of the
number of attributes in each identity (used as public key) but they
also have useful structures which result in more efficient key
extraction and/or encryption than the random oracle version of Sahai
and Water's fuzzy IBE scheme, considered recently by Pirretti et al.
We prove that the confidentiality of the proposed  schemes is
relative to the Bilinear Decisional Bilinear Diffie-Hellman problem.
