BBN Technologies BBN Technologies The Resource Public Key Infrastructure (RPKI) is an authorization infrastructure that allows the holder of Internet Number Resources (INRs) to make verifiable statements about those resources. The certification authorities (CAs) in the RPKI issue certificates to match their allocation of INRs. These entities are trusted to issue certificates that accurately reflect the allocation state of resources as per their databases. However, there is some risk that a CA will make inappropriate changes to the RPKI, either accidentally or deliberately (e.g., as a result of some form of "government mandate"). The mechanisms described below, and referred to as "Suspenders" are intended to address this risk. Suspenders enables an INR holder to publish information about changes to objects it signs and publishes in the RPKI repository system. This information is made available via a file that is external to the RPKI repository, so that Relying Parties (RPs) can detect erroneous or malicious changes related to these objects. RPs can then decide, individually, whether to accept changes that are not corroborated by independent assertions by INR holders, or to revert to previously verified RPKI data.
