In the incoming internet of things (IoT) applications, smart sensors expose services to interact with them, to be parameterised, managed and maintained. Therefore, fine‐grained end‐to‐end access control enforcement is mandatory to tackle the derived security requirements. However, it is still not feasible in very constrained devices. There is an innovative access control model that conveys an expressive policy language and an optimised codification for tight and flexible access control enforcement in very constrained devices. Such tightness enabled by the expressiveness of the policy language leads to detailed policy instances that might impact on the performance and therefore, in the feasibility and further applicability. In this context, this study assesses how the policy length impacts the performance of the establishment of a security association through the protocol named Hidra proposed by such an adapted access control model. Consequently, the notable results of the performance evaluation prove the feasibility and adequacy of this access control model for the new smart IoT scenarios.
