Abstract: | With the rapidly increasing connectivity of an enormous number of devices, a trend has emerged: interconnected devices collaborating to form complex networks that deliver novel services. However, this trend poses a number of novel challenges related to cybersecurity and privacy. These networks typically consist of heterogeneous devices with limited hardware capabilities, intermittent connectivity, and dynamic topologies. These inherent properties create a complex environment for establishing trust within these networks, as traditional methods do not handle the mentioned characteristics effectively. This dissertation focuses on space networks and their specific characteristics. Nevertheless, many of our presented approaches apply to other networks with similar properties. Although the deployment of networked (i.e., multi-hop) communication among satellites is a novelty in its early stages, it will soon exacerbate the growing security concerns in space. The European and American security agencies have recognized this problem's importance and declared space as critical infrastructure in recent years. Ensuring trust in space networks---and other networks with similar properties---will become crucial to ensure the proper functioning of resulting services. In this dissertation, we design, implement, and evaluate 1) schemes to enable Public Key Infrastructures in constrained networks, 2) approaches to enable large-scale remote platform validation, 3) protocols to minimize the reliance on online authorities for networks with collaborating nodes, and 4) an approach to prevent the geolocation of satellite Internet users. |
