Privacy Preserving and Resilient RPKI
Authors: Kris Shrishak (TU Darmstadt); Haya Shulman (Fraunhofer SIT)
Resource Public Key Infrastructure (RPKI) is vital to the security of inter-domain routing. In addition to the security benefits, RPKI also unfortunately enables Regional Internet Registries (RIRs) to unilaterally takedown IP prefixes - indeed, such attacks have been launched by nation-state adversaries. The threat of IP prefix takedowns is one of the factors hindering RPKI adoption. In this work, ATHENE researchers proposed the first distributed RPKI system, based on threshold signatures, that requires the coordination of a number of RIRs to make changes to the RPKI objects; hence, preventing unilateral prefix takedowns by compromised or malicious RIRs. Our researchers perform extensive evaluations using our implementation demonstrating the practicality of our solution. Furthermore, they show that our system is scalable and remains efficient even when RPKI is widely deployed.

INFOCOM 2021 will take place from May 10 - 13, 2021 as a virtual conference.
