Abstract:

Motivated by the difficulties of static passwords, we explore the
security and usability benefits of equipping users with an extremely
limited, wireless (radio-frequency), output-only device. While it may
seem counter-intuitive that a token that accepts no inputs and
broadcasts its output using an untrusted medium can provide any security
benefits, we propose and analyze a family of authentication and
encryption protocols using a unidirectional token. Since unidirectional
security devices seem mostly unexplored in the literature, we appeal to
analysis frameworks for established protocols like Bellare and Rogaway's
AKE. We additionally offer protocols of increasing cryptographic
sophistication while still relying on a unidirectional token. Our
prototype wireless security-token works with standard, Wi-Fi-enabled
personal computers and requires no special-purpose hardware or drivers.
Thanks to a new tunneling protocol, our token allows a computer to
conduct an ongoing conventional 802.11 session and simultaneously
receive token emissions.


Alle Interessierten sind herzlich eingeladen!
