This subproject addresses two fundamental issues in the protection of the Smart Grid: the privacy of user data, and the availability and reliability of the different data networks belonging to its infrastructure. The private user information is one of the assets to be protected in critical infrastructures in general, and in Smart Grids in particular, since it is a fundamental individual right. Apart from the necessary protection against classical security attacks, such as unauthorized access or traffic analysis, we propose to especially investigate those aspects more related to the Smart Grid. In this sense, several mechanisms will be firstly proposed to avoid the profiling of consumption, since the possibility of deducing patterns of social behavior based on energy consumption has been shown. The techniques used in this field are generally based on data aggregation and profile obfuscation. Secondly, techniques used for anonymization statistical databases will be applied to enable the exchange of information between different entities. Particular attention will be given to the inherent compromise between privacy and usability, and in particular to propose and evaluate privacy mechanisms that allow a subsequent efficient analysis of the data. These anonymized databases can be securely shared among different Smart Grid agents, and these data can then be processed using machine learning techniques to improve the management and maintenance of the Smart Grid infrastructure. The second objective of this subproject is to protect data communications by improving the availability and reliability of the different networks that are part of the Smart Grid infrastructure. These communications networks are one of the priority areas currently in research on Smart Grid. We will propose, design and evaluate teletraffic engineering techniques, as well as routing protocols and new associated metrics, in order to improve the service provided to the different traffic flows carried by these networks, while adjusting the amount of allocated resources. The new metrics may include protection against traffic analysis when looking for best paths. Furthermore, as an additional measure to protect energy supply in emergency situations caused by cyberattacks or natural disasters, we will consider the inclusion of new types of elements, as the electric vehicles, as a possible new source of energy. For these new connected devices, we will, on the one hand, characterize the data traffic generated and consumed, and on the other, analyse and satisfy their requirements regarding quality of service, security and privacy.
