Abstract

In this paper we identify and define cryptographic dysfunctionality and within this context we perform a study to evaluate user perceptions of public key cryptography concepts. The study makes use of user testing, questionnaires and wrap-up interviews with 121 young, but experienced Internet users during their interactions with selected secure Internet locations. The results show that the vast majority of users are not familiar with fundamental concepts of cryptography, and that they are not capable of efficiently managing digital certificates. This case study serves as first evidence supporting our hypothesis that user interface design is deteriorating cryptographic solutions effectiveness due to usability issues.
