[en] This paper discusses whether usable security is unattainable for some security tasks due to intrinsic bounds of human cognitive capacities. Will Johnny ever be able to encrypt? Psychology and neuroscience literature shows that there are upper bounds on the human capacity for executing cognitive tasks and for information processing. We argue that the usable security discipline should scientifically understand human capacities for security tasks, i.e., what we can realistically expect from people. We propose a framework for evaluation of human capacities in security that assigns socio-technical systems to complexity classes according to their security and usability. The upper bound of human capacity is considered the point at which people start experiencing cognitive strain while performing a task, because cognitive strain demonstrably leads to errors in the task execution. The ultimate goal of the work we initiate in this paper is to provide designers of security mechanisms or policies with the ability to say:“This feature of the security mechanism X or this security policy element Y is inappropriate, because this evidence shows that it is beyond people’s capacity".
