  • unipass design and evaluation of a smart device based Password Manager for visually impaired users
    Ubiquitous Computing, 2016
    Co-Authors: Nata Miccael Barbosa, Jordan Hayes, Yang Wang
    Abstract:

    Visually impaired users face various challenges in web authentication. We designed UniPass, an accessible Password Manager for visually impaired users based on a smart device. To evaluate UniPass, we tested and compared UniPass with two commercial Password Managers: LastPass, a popular Password Manager and StrongPass, a smart device-based Password Manager. Our study results of ten users, six blind and four with low vision, suggest that Password Managers are a promising authentication approach for visually impaired users. Participants using UniPass had the highest task completion rate and took the shortest time to complete an authentication related task. Furthermore, the majority (seven out of ten) of our participants preferred UniPass over LastPass and StrongPass.

  • tapas design implementation and usability evaluation of a Password Manager
    Annual Computer Security Applications Conference, 2012
    Co-Authors: Daniel Mccarney, David Barrera, Jeremy Clark, Sonia Chiasson, P C Van Oorschot
    Abstract:

    Passwords continue to prevail on the web as the primary method for user authentication despite their well-known security and usability drawbacks. Password Managers offer some improvement without requiring server-side changes. In this paper, we evaluate the security of dual-possession authentication, an authentication approach offering encrypted storage of Passwords and theft-resistance without the use of a master Password. We further introduce Tapas, a concrete implementation of dual-possession authentication leveraging a desktop computer and a smartphone. Tapas requires no server-side changes to websites, no master Password, and protects all the stored Passwords in the event either the primary or secondary device (e.g., computer or phone) is stolen. To evaluate the viability of Tapas as an alternative to traditional Password Managers, we perform a 30 participant user study comparing Tapas to two configurations of Firefox's built-in Password Manager. We found users significantly preferred Tapas. We then improve Tapas by incorporating feedback from this study, and reevaluate it with an additional 10 participants.

  • Financial Cryptography Workshops - Exploration and field study of a Password Manager using icon-based Passwords
    Financial Cryptography and Data Security, 2012
    Co-Authors: Kemal Bicakci, Nart Bedin Atalay, Mustafa Yuceel, P C Van Oorschot
    Abstract:

    We carry out a hybrid lab and field study of a Password Manager program, and report on usability and security. Our study explores iPMAN, a browser-based Password Manager that in addition uses a graphical Password scheme for the master Password. We present our findings as a set of observations and insights expected to be of interest both to those exploring Password Managers, and graphical Passwords.

  • Exploration and Field Study of a Browser-based Password Manager using Icon-based Passwords ?
    2011
    Co-Authors: Kemal Bicakci, Nart Bedin Atalay, Mustafa Yuceel, P C Van Oorschot
    Abstract:

    We carry out a hybrid lab and eld study of a Password Manager program, and report on usability and security. Our study explores iPMAN, a browser-based Password Manager that in addition uses a graphical Password scheme for the master Password. We present our ndings as a set of observations and insights expected to be of interest both to those exploring Password Managers, and graphical Passwords. Motivated by our ndings, but also of independent interest, we also present a new salt generation method using blind signatures, to protect against oine attacks, decreasing user inconvenience by generating salt signicantly faster than earlier work (Halderman et al. 2005).

  • IFIPTM - Graphical Passwords as Browser Extension: Implementation and Usability Study
    Trust Management III, 2009
    Co-Authors: Kemal Bicakci, Mustafa Yuceel, Burak Erdeniz, Hakan Gurbaslar, Nart Bedin Atalay
    Abstract:

    Today, most Internet applications still establish user authentication with traditional text based Passwords. Designing a secure as well as a user-friendly Password-based method has been on the agenda of security researchers for a long time. On one hand, there are Password Manager programs which facilitate generating site-specific strong Passwords from a single user Password to eliminate the memory burden due to multiple Passwords. On the other hand, there are studies exploring the viability of graphical Passwords as a more secure and user-friendly alternative. In this paper, we present GPEX, a Password Manager program implemented as a web browser plug-in to enable using graphical Passwords to secure Internet applications without any need to change their authentication interface. Experimental results show that GPEX has security and usability advantages over other Password Manager plug-ins. specifically; we find that with the visual interface of GPEX, users have a more complete and accurate mental model of the system and incorrect login attempts causing security exposures can easily be avoided.
