Abstract Multi-factor authentication is a security system, which contains more than one form of authentication system implemented to verify a user’s identity. For example, this system could contain biometrics, tokens / smart cards, or password-based authentication solutions. By using the combination of these different authentication systems, the authentication process will become stronger, and the security will get enhanced. The first part of thesis is focusing on multi-factor authentication technologies and business issues, viewing available authentication solutions which could support and be integrated into multi-authentication framework. A selection will be offered after the comparison of most of the authentication systems. Finally we choose Keystroke Dynamics and Ranking password as our authentication systems. In the second part of the thesis, a new authentication framework model called “Jury” was introduced. This framework is from Einar Jonsson’s thesis work “Co-Authentication: A Probabilistic Approach to Authentication”. Jury has the ability of combining the results of one or more authentication systems in a probabilistic way. One big challenge is the integration of two different authentication systems into the Jury framework. After a study on Jury and get familiar with socket programming, we design and implement a multi-factor authentication system, which is based on Jury framework. In this system, we develop two different authentication systems such as keyboard biometric and ranking password. We also develop a remote protected system by using traditional client-server way. We make the suitable authentication systems to a threshold-based scheme, and write JIN wrappers for them to communicate with Jury. By using and extending “Jury” infrastructure, finally we will get more detailed evaluation of a multi-factor system’s performance, reliability and usability.
