SAMGRID: Security Authorization and Monitoring Module Based on SealedGRID Platform.

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.

SealedGRID: Secure and Interoperable Platform for Smart GRID Applications.

Recent advancements in information and communication technologies (ICT) have improved the power grid, leading to what is known as the smart grid, which, as part of a critical economic and social infrastructure, is vulnerable to security threats from the use of ICT and new emerging vulnerabilities and privacy issues. Access control is a fundamental element of a security infrastructure, and security is based on the principles of less privilege, zero-trust, and segregation of duties. This work addresses how access control can be applied without disrupting the power grid's functioning while also properly maintaining the security, scalability, and interoperability of the smart grid. The authentication in the platform presumes digital certificates using a web of trust. This paper presents the findings of the SealedGRID project, and the steps taken for implementing Attribute-based access control policies specifically customized to the smart grid. The outcome is to develop a novel, hierarchical architecture composed of different licensing entities that manages access to resources within the network infrastructure. They are based on well-drawn policy rules and the security side of these resources is placed through a context awareness module. Together with this technology, the IoT is used with Big Data (facilitating easy handling of large databases). Another goal of this paper is to present implementation and evaluations details of a secure and scalable security platform for the smart grid.

An Intelligent Low-Power Displaying System withIntegrated Emergency Alerting Capability.

Integrated communication infrastructure has become a must-have facility for modernpublic buildings and offices. To cover this need, several commercial products exist on the market,but most of them require advanced technical skill to operate, while others require manual and timeconsumingoperations. This work proposes an intelligent displaying and alerting system (calledSICIAD), implemented over an integrated communication infrastructure with support for wirelessePaper and iBeacon technologies to enhance displaying static and dynamic information, as well asto ease the indoor orientation of guests. A centralized display management console is implemented,as well as procedures for automatically displaying different types of notifications. An Androidmobile application is developed which enables indoor user location and guidance. The systemtargets educational and research institutions but could also cope with public institutions such asmuseums and hospitals. Remote authentication is supported in research facilities through eduroamtechnology, access being provided by the user's distant institution of affiliation. Secure multiplelevelaccess to the system is provided to users, from guests to system administrators, based onlocally defined policies. Functional validation and performance evaluation aspects are presented forthe proposed system.
