New on RIPE Labs: Future Internet at Terabit Speeds - SCION in P4
by Alun Davies 27 May '21

27 May '21

Dear colleagues, As part of the 2STiC programme, SIDN Labs evaluates and experiments with future Internet architectures. One of these is SCION. In this guest post on RIPE Labs, Joeri de Router and Caspar Schutijser introduce the high-speed SCION router prototype they implemented to find out if a complex protocol such as SCION can run directly on hardware using the flexibility provided by P4. https://labs.ripe.net/author/joeri-de-ruiter/future-internet-at-terabit-spe… Kind regards, Alun Davies RIPE Labs Editor RIPE NCC

New on RIPE Labs: SCION - A Novel Internet Architecture
by Alun Davies 17 May '21

17 May '21

Dear colleagues, At RIPE 81, a group of enthusiastic researchers and practitioners from industry and academia discussed with the RIPE community what role RIRs and LIRs could take on in the SCION next-generation Internet architecture. Ahead of the second SCION BoF taking place today at RIPE 82, David Hausheer looks back at what happened at the last BoF, reports on what has happened since then, and presents what potential RIPE involvement could look like in the future.

Security & Compliance reports for RPKI
by Nathalie Trenaman 10 May '21

10 May '21

Dear colleagues, Security is always high on our list of priorities for RPKI. Every year, we ask an external party to carry out a security audit of our RPKI systems. This is the first year that we are publishing the security report, in an effort to increase transparency and trust in the RPKI system. Please note that the report also listed several recommendations that should be included in a penetration test. These recommendations have been redacted from the original report, as we will include them in the penetration test scheduled for June 2021. Also, some comments about the proprietary software for the Hardware Security Module have been redacted. On https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/security-… you will now find the RFC compliance report written by Radically Open Security in 2020 and our response to their findings. We hope you will find these reports useful, and we look forward to your feedback. Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

Dear colleagues, The mission critical services the RIPE NCC provides to the Internet community require a solid technical foundation. In this new article on RIPE Labs, Felipe Silveira looks at plans to use cloud infrastructure as a means to that end. The full article is available here: https://labs.ripe.net/author/felipe_victolla_silveira/rpki-repositories-and… Kind regards, Alun Davies RIPE Labs Editor RIPE NCC

We all - community, legislators, etc - agree on the importance of routing security. The only concern I had was whether codifying specific ways of handling this was advisable, but if they're not being codified, that's fine. Nick
