I'm saying that if ISPs aren't the only entities that hold their private keys, then they aren't the only entities that can sign their resources. If you choose to delegate the CA role for signing your resources to someone else, then, obviously, you have to give them a valid private key with which to sign those resources. However, in doing that, you've created a situation where your signature is now much easier to forge. Kind of like automatic signing machines for checks. Benefit: The accounting department can sign thousands of checks and the CFO doesn't have to. Draw-back... The accounting department can sign thousands of checks without the CFO knowing they did so.

The reason to offer a hosted system initially, is to take away the burden from an LIR of having to run their own Certificate Authority. We offer a service that makes the entry barrier for Certification as low as possible. Properly running your own CA, with all the crypto aspects, is no small feat for a lot of LIRs (technically, but perhaps more psychologically). You may argue that it's easy and cheap to do yourself, but just look at adoption rates and levels of IPv6 and DNSSEC *at an LIR level* to see what reality is like. After the production launch on 1 January 2011, the next step we will take is to implement the up/down protocol, allowing people to run their own Certificate Authority if they choose to do so. We plan to roll this out in the first half of 2011. We'll go one step further by having our software certified by an external independent company, and releasing it as open source to the Community, so they can be sure they adopt a robust system if they choose our package. So in the end our implementation is not 'broken' as you say, it is in he middle of a planned, phased approach. Not everything is possible yet and that is a deliberate decision. > I'll go a step further and say that the resource holder should be > the ONLY holder of the private key for their resources. > > Owen If you're saying that ISPs can only participate in an RPKI scheme if they run their own Certificate Authority, then I think that would practically ruin the chances of Certification actually ever taking off on a large scale. -Alex

RPKI Resource Certification: building features
by Alex Band 03 Oct '10

03 Oct '10

Most of the discussions around RPKI Resource Certification that have been held up to now have largely revolved around infrastructure and policy topics. I would like to move away from that here and discuss what kind of value and which features can be offered with Certification for network administrators around the world. Because in the end, the goal is to make Internet routing more robust and create a more reliable method for network operators to make routing decisions. We all know about the shortcomings of the IRR system and that just half of all prefixes on the Internet have a route object associated with them (http://bgpmon.net/blog/?p=140). However, it does mean that there is ton of valuable information in the IRRs, whereas the Certification system needs to start from scratch. Based on many discussion I've had with members and the Community, here is my idea for a Route Origin Authorisation** (ROA) wizard that retrieves IRR information, compares it to real world routing and uses that for the creation of ROA Specifications. This has a number of benefits: - Network operators don't have to create their routing policy in the Certification system from scratch - Because a comparison between is done the IRR and RIS (http://ripe.net/ris/), only accurate up-to-date information is added to the Certification system - The accuracy of the IRR is increased as a bonus, and is achieved without leaving the wizard Ideally, a network operator should be able to manage and publish their routing policy – both for the IRR and Certification – from one single interface. Here are the basic steps for the wizard after a certificate is generated: 1. Start ROA Wizard 2. Detect IRR information using the AS numbers in the Certificate, like for example: http://www.db.ripe.net/whois?searchtext=AS286&inverse_attributes=origin&for… 3: Compare results with RIS using RRCC/Netsense, like for example: http://www.ris.ripe.net/cgi-bin/rrccng/query.cgi?target=AS286 4: Allow user to flag which ROA specifications they would actually like to create, based on the IRR and RRCC/Netsense results. 5: Allow user to create additional ROA Specifications 6: Detect which maintainer is used for the route objects in the IRR 7: Allow user to specify maintainer password/pgp key, so all route objects are updated/removed/added based on the ROAs that were created. This makes sure the data in the IRR and the Certification system is consistent. 8: Save and publish ROAs and route objects Do you think there is value in creating a system like this? Are there any glaring holes that I missed, or something that could be added? I'm looking forward to your feedback. Alex Band RIPE NCC http://ripe.net/certification ** The certification system largely revolves around three main elements: (1) the Certificate, that offers validated proof of holdership of an Internet Resource, (2) the Route Orgin Authorisation Object (ROA), a standardised document that states that the holder of a certain prefix authorises a particular AS to announce that prefix and (3) the Validator, which relying parties, i.e. your peers, can use to validate certificates and ROAs.
