RFC8481 - Clarifications to BGP Origin Validation Based on Resource Public Key Infrastructure (RPKI): Deployment of BGP origin validation based on Resource Public Key Infrastructure (RPKI) is hampered by, among other things, vendor misimplementations in two critical areas: which routes are validated and whether policy is applied when not specified by configuration. This document is meant to clarify possible misunderstandings causing those misimplementations; it thus updates RFC 6811 by clarifying that all prefixes should have their validation state set and that policy must not be applied without operator configuration.
RFC8488 - RIPE NCC's Implementation of Resource Public Key Infrastructure (RPKI) Certificate Tree Validation: This document describes an approach to validating the content of the Resource Public Key Infrastructure (RPKI) certificate tree, as it is implemented in the RIPE NCC RPKI Validator. This approach is independent of a particular object retrieval mechanism, which allows it to be used with repositories available over the rsync protocol, the RPKI Repository Delta Protocol (RRDP), and repositories that use a mix of both.
RFC8608 - BGPsec Algorithms, Key Formats, and Signature Formats: This document specifies the algorithms, algorithm parameters, asymmetric key formats, asymmetric key sizes, and signature formats used in BGPsec (Border Gateway Protocol Security). This document updates RFC 7935 ("The Profile for Algorithms and Key Sizes for Use in the Resource Public Key Infrastructure") and obsoletes RFC 8208 ("BGPsec Algorithms, Key Formats, and Signature Formats") by adding Documentation and Experimentation Algorithm IDs, correcting the range of unassigned algorithms IDs to fill the complete range, and restructuring the document for better reading.; This document also includes example BGPsec UPDATE messages as well as the private keys used to generate the messages and the certificates necessary to validate those signatures.
RFC8630 - Resource Public Key Infrastructure (RPKI) Trust Anchor Locator: This document defines a Trust Anchor Locator (TAL) for the Resource Public Key Infrastructure (RPKI). The TAL allows Relying Parties in the RPKI to download the current Trust Anchor (TA) Certification Authority (CA) certificate from one or more locations and verify that the key of this self-signed certificate matches the key on the TAL. Thus, Relying Parties can be configured with TA keys but can allow these TAs to change the content of their CA certificate. In particular, it allows TAs to change the set of IP Address Delegations and/or Autonomous System Identifier Delegations included in the extension(s) (RFC 3779) of their certificate.; This document obsoletes the previous definition of the TAL as provided in RFC 7730 by adding support for Uniform Resource Identifiers (URIs) (RFC 3986) that use HTTP over TLS (HTTPS) (RFC 7230) as the scheme.
RFC8634 - BGPsec Router Certificate Rollover: Certification Authorities (CAs) within the Resource Public Key Infrastructure (RPKI) manage BGPsec router certificates as well as RPKI certificates. The rollover of BGPsec router certificates must be carefully performed in order to synchronize the distribution of router public keys with BGPsec UPDATE messages verified with those router public keys. This document describes a safe rollover process, and it discusses when and why the rollover of BGPsec router certificates is necessary. When this rollover process is followed, the rollover will be performed without routing information being lost.
RFC8635 - Router Keying for BGPsec: BGPsec-speaking routers are provisioned with private keys in order to sign BGPsec announcements. The corresponding public keys are published in the Global Resource Public Key Infrastructure (RPKI), enabling verification of BGPsec messages. This document describes two methods of generating the public-private key pairs: router-driven and operator-driven.
RFC8893 - Resource Public Key Infrastructure (RPKI) Origin Validation for BGP Export: A BGP speaker may perform Resource Public Key Infrastructure (RPKI) origin validation not only on routes received from BGP neighbors and routes that are redistributed from other routing protocols, but also on routes it sends to BGP neighbors. For egress policy, it is important that the classification use the 'effective origin AS' of the processed route, which may specifically be altered by the commonly available knobs, such as removing private ASes, confederation handling, and other modifications of the origin AS. This document updates RFC 6811.
RFC8897 - Requirements for Resource Public Key Infrastructure (RPKI) Relying Parties: This document provides a single reference point for requirements for Relying Party (RP) software for use in the Resource Public Key Infrastructure (RPKI). It cites requirements that appear in several RPKI RFCs, making it easier for implementers to become aware of these requirements. Over time, this RFC will be updated to reflect changes to the requirements and guidance specified in the RFCs discussed herein.
RFC9255 - The 'I' in RPKI Does Not Stand for Identity: There is a false notion that Internet Number Resources (INRs) in the RPKI can be associated with the real-world identity of the 'holder' of an INR. This document specifies that RPKI does not associate to the INR holder.
RFC9286 - Manifests for the Resource Public Key Infrastructure (RPKI): This document defines a "manifest" for use in the Resource Public Key Infrastructure (RPKI). A manifest is a signed object (file) that contains a listing of all the signed objects (files) in the repository publication point (directory) associated with an authority responsible for publishing in the repository. For each certificate, Certificate Revocation List (CRL), or other type of signed objects issued by the authority that are published at this repository publication point, the manifest contains both the name of the file containing the object and a hash of the file content. Manifests are intended to enable a relying party (RP) to detect certain forms of attacks against a repository. Specifically, if an RP checks a manifest's contents against the signed objects retrieved from a repository publication point, then the RP can detect replay attacks, and unauthorized in-flight modification or deletion of signed objects. This document obsoletes RFC 6486.
RFC9319 - The Use of maxLength in the Resource Public Key Infrastructure (RPKI): This document recommends ways to reduce the forged-origin hijack attack surface by prudently limiting the set of IP prefixes that are included in a Route Origin Authorization (ROA). One recommendation is to avoid using the maxLength attribute in ROAs except in some specific cases. The recommendations complement and extend those in RFC 7115. This document also discusses the creation of ROAs for facilitating the use of Distributed Denial of Service (DDoS) mitigation services. Considerations related to ROAs and RPKI-based Route Origin Validation (RPKI-ROV) in the context of destination-based Remotely Triggered Discard Route (RTDR) (elsewhere referred to as "Remotely Triggered Black Hole") filtering are also highlighted.
RFC9323 - A Profile for RPKI Signed Checklists (RSCs): This document defines a Cryptographic Message Syntax (CMS) protected content type for use with the Resource Public Key Infrastructure (RPKI) to carry a general-purpose listing of checksums (a 'checklist'). The objective is to allow for the creation of an attestation, termed an "RPKI Signed Checklist (RSC)", which contains one or more checksums of arbitrary digital objects (files) that are signed with a specific set of Internet Number Resources. When validated, an RSC confirms that the respective Internet resource holder produced the RSC.
RFC9324 - Policy Based on the Resource Public Key Infrastructure (RPKI) without Route Refresh: A BGP speaker performing policy based on the Resource Public Key Infrastructure (RPKI) should not issue route refresh to its neighbors because it has received new RPKI data. This document updates RFC 8481 by describing how to avoid doing so by either keeping a full Adj-RIB-In or saving paths dropped due to ROV (Route Origin Validation) so they may be reevaluated with respect to new RPKI data.
RFC9455 - Avoiding Route Origin Authorizations (ROAs) Containing Multiple IP Prefixes: When using the Resource Public Key Infrastructure (RPKI), address space holders need to issue Route Origin Authorization (ROA) object(s) to authorize one or more Autonomous Systems (ASes) to originate BGP routes to IP address prefix(es). This memo discusses operational problems that may arise from ROAs containing multiple IP prefixes and recommends that each ROA contain a single IP prefix.
