UPIN
User Driven Path Verification and Control for Inter-Domain Networks
The goal of UPIN is to develop and evaluate a scalable distributed system that enables users to cryptographically verify and easily control the paths through which their data travels through an inter-domain network like the Internet, both in terms of router-to-router hops as well as in terms of router attributes (e.g., their location, operator, security level, and manufacturer). UPIN will thus provide the solution to a very relevant and current problem, namely that it is becoming increasingly opaque for users on the Internet who processes their data (e.g., in terms of service providers their data passes through as well as what jurisdictions apply) and that they have no control over how it is being routed. This is a risk for people’s privacy (e.g., a malicious network compromising a user’s data) as well as for their safety (e.g., an untrusted network disrupting a remote surgery).

Standards and open source software development for internet infrastructure, security and resilience.
Hands-on experience with emerging internet technologies, like segment-routing and network programmability (Openflow, P4, eBPF).
Operating multi-site critical infrastructure, measurement-based research and technology development on Internet security and resilience, protocol standardization.
Most users of the Internet do not know how their traffic flows through the network to its final destination and cannot verify or control its path. The targeted impact is twofold: Increased trust from users (individuals and organizations) in network services because they areable to verify how their data travels through the network to the destination endpoint, and More empowered users because they are able to control how their data travels throughinter-domain networks, which increases self-determination.
