Title: Password hardening based on keystroke dynamics

Abstract:

We present a novel approach to improving the security of passwords. In
our approach, the legitimate user's typing patterns (e.g., durations of
keystrokes, and latencies between keystrokes) are combined with the
user's password to generate a "hardened password" that is convincingly
more secure than conventional passwords against both online and offline
attackers. In addition, our scheme automatically adapts to gradual
changes in a user's typing patterns while maintaining the same hardened
password across multiple logins, for use in file encryption or other
applications requiring a long-term secret key. We describe applications
of this technology to improving security in virtual private networks,
and further describe the results of trials we have conducted to
empirically evaluate this technology. These results suggest that our
approach is viable in practice, in terms of ease of use, improved
security, and performance. This is joint work with Fabian Monrose and
Susanne Wetzel.

Bio:

Michael Reiter (www.bell-labs.com/user/reiter) is Department Head of the

Secure Systems Research Department in Bell Laboratories, Lucent
Technologies. He received the B.S. degree in mathematical sciences from
the University of North Carolina in 1989, and the M.S. and Ph.D. degrees

in computer science from Cornell University in 1991 and 1993,
respectively. He joined AT&T Bell Labs in 1993 and became a founding
member of AT&T Labs Research when NCR and Lucent Technologies (including

Bell Labs) were split away from AT&T in 1996. He returned to Bell Labs
in 1998 to take his current position. During 1998-2000, he will serve as

Program Chair of the flagship computer security conferences of both the
Association for Computing Machinery (ACM) and the Institute of
Electrical and Electronic Engineers (IEEE), and serves on numerous other

conference program committees in the areas of computer security and
distributed computing. Dr. Reiter's research interests include all areas

of computer and communications security, electronic commerce, and
distributed computing.
