摘要

Abstract

We propose a new biometric identity based encryption scheme (Bio-IBE)

in which user biometric information is used to generate the public key with a fuzzy extractor. This is the ﬁrst Bio-IBE scheme that achieves constant size ciphertext. This is also a scheme that is secure against the adaptive chosen ciphertext attack (CCA2). Details are presented along with a discussion of Shamir’s threshold secret sharing and fuzzy extraction of biometrics

which is based on error correction codes. We also deﬁne a security model and prove that the security of the proposed scheme is reduced to the decisional bilinear Diﬃe-Hellman (DBDH) assumption. The comparison shows that the proposed scheme has better eﬃciency and stronger security compared with the available Bio-IBE schemes.
