Abstract Multi-factor authentication (MFA) was proposed by Pointcheval et al. [Pointcheval
and Zimmer (2008)] to improve the security of single-factor (and two-factor) authentication.
As the backbone of multi-factor authentication, biometric data are widely observed. Especially,
how to keep the privacy of biometric at the password database without impairing efficiency is
still an open question. Using the vulnerability of encryption (or hash) algorithms, the attacker
can still launch offline brute-force attacks on encrypted (or hashed) biometric data. To address
the potential risk of biometric disclosure at the password database, in this paper, we propose a
novel efficient and secure MFA key exchange… More >
