Our paper Towards More Practical Software-based Attestation has been accepted for publication by Elsevier’s Computer Networks Journal. Authors: Rodrigo Vieira Steiner, Emil Lupu Abstract: Software-based attestation promises to enable the integrity verification of untrusted devices without requiring any particular hardware. However, existing proposals rely on strong assumptions that hinder their deployment and might even weaken their security. One of such assumptions is that using the maximum known network round-trip time to define the attestation timeout allows all honest devices to reply in time. While this is normally true in controlled environments, it is generally false in real deployments and especially so in a scenario […]

Our paper WSNs Under Attack! How Bad Is It? Evaluating Connectivity Impact Using Centrality Measures has been presented at the Living in the Internet of Things: A PETRAS, IoTUK & IET Conference, Forum & Exhibition. Authors: Rodrigo Vieira Steiner, Martín Barrère, Emil C. Lupu Abstract: We propose a model to represent the health of WSNs that allows us to evaluate a network’s ability to execute its functions. Central to this model is how we quantify the importance of each network node. As we focus on the availability of the network data, we investigate how well different centrality measures identify the significance of each node for the […]
