policy proposal: "Automatic Revocation of Persistently Non-functional Delegated RPKI CAs"
by Job Snijders 25 Apr '25

25 Apr '25

Dear all, I'd like to propose a mechanism to automatically prune dead branches in the RPKI directly subordinate to RIPE NCC. Below is the policy proposal text that I have in mind. In short: RIPE NCC should revoke a Delegated CA's certificate when absolutely no "sign of life" (valid Manifest) has been observed for over a 100 days. It probably is good to have some discussion around: * should perpetually broken Delegated CA setups be culled at some point? * is the continuous lack of a valid current manifest for a 100 day period of time a good indicator for "Delegated CA brokenness"? Your feedback is most welcome! Kind regards, Job ------------------- Policy Proposal Name: Automatic Revocation of Persistently Non-functional Delegated RPKI Certification Authorities Author: a. name: Job Snijders b. email: job(a)sobornost.net Proposal Version: (to be assigned by the RIPE NCC) Submission Date: February 25th, 2025 Suggested RIPE WG for discussion and publication: RIPE Routing Working Group Proposal Type: NEW Policy Term: Indefinite Summary of proposal: RIPE NCC offers users of its RPKI certification service two deployment models: "Hosted CA setup" and "Delegated CA setup". In the Hosted setup RIPE NCC is responsible for timely issuance and publication of new RPKI Manifests and CRLs, but in the Delegated setup users themselves manage their CA on their own infrastructure. It is possible for Delegated CA infrastructure to be offline for extended periods of time or for the contents of publication repositories to become stale or otherwise invalid. This proposal suggests to provide mandate to RIPE NCC to revoke resource certificates associated with longtime non-functional CAs to reduce Relying Party workload. This policy proposal targets only pathologically non-functional CAs. An example of a situation considered out-of-scope for this policy would be a publication repository service advertised to also be available via IPv6 and RRDP but in practise only reachable via IPv4 and Rsync: the associated CA would still be considered functional (provided a valid and current Manifest could somehow be retrieved and validated sometime in the previous one hundred days). In other words: this policy proposal isn't about CAs that didn't achieve 100% uptime, but about CAs that are down all the time. Policy text: If RIPE NCC is unable to discover and validate a Delegated RPKI Certification Authority's (CA's) current Manifest and CRL for one hundred consecutive days, that Delegated CA's resource certificate shall be revoked by the RIPE NCC. RIPE NCC shall make reasonable efforts to discover new Manifests, for example, by corroborating information from multiple vantage points. After revocation, the Resource Holder may either reinitialize the Delegated CA setup or choose the Hosted CA setup. Rationale: a. Arguments supporting the proposal Persistently Non-functional Delegated CAs (PNDCs, for short) have subtle effects within the RPKI ecosystem which may become more pronounced over time. * PNDCs offer nothing of value to RPs (because without a current valid Manifest any signed payloads are unavailable). * RP synchronisation becomes more economic with fewer purposeless caRepositories to traverse. * PNDCs besmirch Relying Party (RP) syslog message archives and waste RP CPU cycles and network traffic. * Automatic revocation is only a minor inconvenience for CAs (that already were non-functional to begin with), but a big deal for RPs - especially when taking into account many future synchronisation attempts over long periods of time. b. Arguments opposing the proposal * Resource holders might require more than one hundred days to complete the initial Delegated CA setup. (Counterpoints: initial setup procedures usually only takes a few minutes. Resource holders are free to simply retry the delegated CA setup procedure following automatic revocation.) Additional opposing arguments to be determined.
