Continuous Remote Attestation Process in the scenario of the ROOT time precision distribution network

Nowadays the trustworthiness, accuracy and availability of time information distributed over networks of every kind is becoming more and more relevant due to the birth of several applications that require accurate and secure time and an high-precision synchronization among their components. Several kinds of threats can be identified in this type of distribution networks, attacks can be run starting from the transmission of the time data until the moment when the information is elaborated by the node. A particular type of networks in which time becomes of primary importance are the 5G telecommunications networks. In order to provide the expected Quality of Service, synchronization is needed in time-precision networks like this. Together with the distribution issue, the elaboration of the information received, that has to be forwarded right after, become fundamental too. Some telecommunication networks are classified as critical infrastructure thus need particular robustness against cyberattacks. In this paper, we identify several type of attacks that can be run against these networks focusing our attention on software attacks that are run trying to take control of a particular machine or simply to install some code on it or to change its configuration. The goal of the thesis is to find a way to detect if an attack like this happens and to report this as quickly as possible, by monitoring the platform status constantly and notifying an anomaly as soon as it is detected, following the principles of the Remote Attestation process.
