In highly dynamic systems resources may have to be accessed in real-time, within the strict time limits of underlying physical processes, with availability becoming critical. Current access control models such as RBAC and ABAC do not address real-time availability in a scalable way for such scenarios. In this paper we propose a real-time attribute-based access control model that extends the functionality of ABAC by using real-time attributes that reflect the requirements of critical applications. We describe two applications of our model: (a) a substation automation system, and (b) a medical cyber-physical system.
