Secure Internet Routing with RPKI

Remy de Boer

• 30 Oct 2014

• 6 min read

Last week we improved the security of our routing infrastructure by implementing RPKI (Resource Public Key Infrastructure), a technology that can be used to secure the Internet routing infrastructure. RPKI was the topic of my Master's thesis and in this article I am trying to convince you to use th…

Experiment Proposal to Improve K-root

Suzanne Taylor

• 29 Oct 2014

• 4 min read

We used RIPE Atlas to measure latency times to K-root, and we believe we can improve those times by adding new nodes to K-root in strategic locations. Here, we propose the idea of developing an experiment that would let us measure this potential improvement.
