Abstract

Evaluating novel authentication systems is often costly and time-consuming. In this work, we assess the suitability of using Virtual Reality (VR) to evaluate the usability and security of real-world authentication systems. To this end, we conducted a replication study and built a virtual replica of CueAuth [52], a recently introduced authentication scheme, and report on results from: (1) a lab-based in-VR usability study (N=20) evaluating user performance; (2) an online security study (N=22) evaluating system’s observation resistance through virtual avatars; and (3) a comparison between our results and those previously reported in the real-world evaluation. Our analysis indicates that VR can serve as a suitable test-bed for human-centred evaluations of real-world authentication schemes, but the used VR technology can have an impact on the evaluation. Our work is a first step towards augmenting the design and evaluation spectrum of authentication systems and offers ground work for more research to follow.

CueVR: Studying the Usability of Cue-based Authentication for Virtual Reality
AVI '22: Proceedings of the 2022 International Conference on Advanced Visual Interfaces

Existing virtual reality (VR) authentication schemes are either slow or prone to observation attacks. We propose CueVR, a cue-based authentication scheme that is resilient against observation attacks by design since vital cues are randomly generated and ...
RubikAuth: Fast and Secure Authentication in Virtual Reality
CHI EA '20: Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems

There is a growing need for usable and secure authentication in virtual reality (VR). Established concepts (e.g., 2D graphical PINs) are vulnerable to observation attacks, and proposed alternatives are relatively slow. We present RubikAuth, a novel ...
Fast and Secure Authentication in Virtual Reality Using Coordinated 3D Manipulation and Pointing
