Robust and secure connectivity is a basic requirement for reliable communication over distributed networks. Specifically, robust connectivity indicates that communication can be sustained even in the face of rapid dynamics, node mobility, node and link failures, and unreliable communication channels, while secure connectivity indicates that the communication is over secure channels, from intended source to the intended destination. In this dissertation, we will investigate robust and secure connectivity in two broad types of networks, one is highly dynamic IoT networks that are often of small scales, and the other is the large-scale Internet.
First, we explore achieving robust connectivity in highly dynamic IoT networks. We design two efficient deterministic group-based neighbor discovery algorithms that provide a rigorous guarantee on expected discovery time in group settings, and can still be succinctly described. Both schemes are lightweight and easy to implement, requiring no explicit communication among the nodes in the group to coordinate the discovery of a new node. Building on the neighbor discovery algorithms, we design multi-copy proactive transmission techniques to achieve low-latency robust connectivity between any pair of nodes in the network. Second, we explore achieving secure connectivity in the Internet, by enhancing the security of inter-domain routing, the glue that connects all the autonomous systems into a global infrastructure. We extend Route Origin Validation (ROV), the basis for the IETF defenses of inter-domain routing, by designing ROV++, a novel extension of ROV. Through extensive simulation and analysis, we show ROV++ provides significantly improved security benefits over ROV, even with partial adoption. Last, we present current work on further improving the security of inter-domain routing.
