    Abstract

    User authentication is a key technology in human machine interaction. The need to establish the legitimacy of transactions and possibly the actors behind them is crucial for trustworthy operation of services over the internet. A good authentication method offers security, usability and privacy protections for the users and the service providers. However, achieving all three properties with a single method is a difficult task and such methods are not in wide use today. We combine methods from biometrics, secure key exchange algorithms and privacy-protecting authentication to build an authentication system that achieves these three properties. Our system uses keystroke dynamics to authenticate the user and cryptographic methods to protect the privacy of the templates and samples and to extend the authentication to key exchange. The results show that the system can be used for user authentication, but more work is needed to protect against impersonation in some cases. Our work is extensible to many other biometrics that can be measured and compared in a similar manner as keystroke dynamics and with further research to larger classes of authentication methods.
