Abstract
Research in the field of usable security and privacy suffered in recent times due to the lack of systematic approach for evaluating the usability of security APIs. As a solution to this problem, we proposed a Cognitive Dimensions Framework (CDF) based methodology to evaluate the usability of security APIs [1,2]. Thereafter, we conducted an empirical investigation to evaluate the proposed methodology. In this evaluation, we employed the proposed methodology to evaluate the usability of four security APIs (Java Secure Socket Extension (JSSE) API, Bouncy Castle lightweight crypto API, OWASP Enterprise Security API, Google authentication API). We expected to evaluate the proposed methodology by measuring its thoroughness, validity, effectiveness, and reliability.
This data set includes the study material used in this experiment, which includes the CDF based questionnaire and the task guidelines (including code artifacts) used for each component of the study.
Results revealed that the proposed methodology identified 80% of the usability issues of each APIs with only seven participant programmers [3]. It was also observed that the validity of the issues identified was between 60% - 80% in all four evaluations [3]. In addition to these findings about the proposed usability evaluation methodology, the results of this study revealed interesting details about usability issues that exist in the four security APIs that were mentioned above [4-7].
