RT Journal Article T1 SAMGRID: Security Authorization and Monitoring Module Based on SealedGRID Platform A1 Suciu, George A1 Farao, Aristeidis A1 Bernardinetti, Giorgio A1 Palamà, Ivan A1 Sachian, Mari-Anais A1 Vochin, Marius-Constantin A1 Muresan, Pavel A1 Bampatsikos, Michail A1 Muñoz-Gallego, Antonio Román A1 Xenakis, Christos K1 Seguridad informática AB IoT devices present an ever-growing domain with multiple applicability. This technology has favored and still favors many areas by creating critical infrastructures that are as profitable as possible. This paper presents a hierarchical architecture composed of different licensing entities that manage access to different resources within a network infrastructure. They are conducted on the basis of well-drawn policy rules. At the same time, the security side of these resources is also placed through a context awareness module. Together with this technology, IoT is used and Blockchain is enabled (for network consolidation, as well as the transparency with which to monitor the platform). The ultimate goal is to implement a secure and scalable security platform for the Smart Grid. The paper presents the work undertaken in the SealedGRID project and the steps taken for implementing security policies specifically tailored to the Smart Grid, based on advanced concepts such as Opinion Dynamics and Smart Grid-related Attribute-based Access Control.
