Feasibility assessment of a fine-grained access control model on resource constrained sensors

Abstract

[ES] Upcoming smart scenarios enabled by the Internetof Things (IoT) envision smart objects that exposeservices that can adapt to user behaviour or be managedfor higher productivity. In such environments, smart thingsare cheap and, therefore, constrained devices. However, theyare also critical components because of the importance ofthe information they provide. Therefore, strong securityis a must, but not all access control models are feasible.In this paper, we propose the feasibility assessment of anaccess control model that deals with a hybrid architectureand a policy language that provides dynamic fine-grainedpolicy enforcement in the sensors, which requires an efficientmessage exchange protocol called Hidra. This experimentalperformance assessment conveys a prototype implementation,a performance evaluation model, the measurements and therelated discussions, which demonstrate the feasibility andadequacy of the analysed access control model.
