What parts of usable security are most important to users?

This paper builds on previous work and investigates what usability factors users prioritize and what demographic factors that affects the perception of usability factors. This is done through a survey answered by 1452 respondents from Sweden, Italy and UK. The results show that users prefer security functions to minimize resource consumption in terms of cost, device performance and time. The study further demonstrates that users want security functions to require as little effort as possible and just work. Further, the study determines that nation of residence and IT competence greatly impacts the perception of usability for security functions while gender and age do so to a much lesser extent.
