Abstract
Biometrics play an increasingly important role in the context
of access control techniques as they promise to overcome the problems of
forgotten passwords or passwords that can be guessed easily. In this
context we discuss a technique to reliably generate a cryptographic key
from biometrics such as a user's typing patterns (e.g. durations of
keystrokes, and latencies between keystrokes) or a user's voice while
speaking a pass-phrase. The generated "hardened password" is more secure
than conventional passwords against both online and offline attackers.
In this talk we also discuss a formal definition of the notion of secret
locking which generalizes the previously described methods. In
addition, we introduce an extended framework to analyze the security of
the scheme.
Bio
Dr. Wetzel is an Assistant Professor at the Computer Science
Department of Stevens Institute of Technology. She received her Diploma
in Computer Science from the University in Karlsruhe (Germany) and a
doctoral degree in Computer Science from Saarland University (Germany)
in 1998. Subsequently, she worked at DaimlerChrysler Research (Stuttgart,
Germany), Lucent Technologies-Bell Laboratories (Murray Hill, USA) and
RSA Laboratories (Stockholm, Sweden).
Dr. Wetzel's research interests are in cryptography and algorithmic
number theory. In the field of cryptography, her research is focused on
wireless security, secret sharing, privacy, and biometrics, and her
contributions range from analysis to protocol design. In algorithmic
number theory, her research is centered on lattice theory, in
particular on developing new algorithms and heuristics for lattice
basis reduction.
