The sidr working group is in wglc for the draft draft-ietf-sidr-slurm-04, "Simplified Local internet nUmber Resource Management with the RPKI".

The draft specifies a mechanism that could be of interest to the operators here.  As the draft says "SLURM allows an operator to create a local view of the global RPKI”.

It would be good to get some eyes here to review the draft.  If you have comments, please do bring them to the wglc in sidr.

However, it should be noted that such collisions are probably irrelevant here. A ‘malicious' CA can always issue another router certificate for an existing (and requested) router certificate SKI and public key. So ‘collisions’ can exist anyway and a more secure hashing algorithm would not help.

Personally I don’t see a big issue here - and would leave it to operators to use the options as they see fit.  But if there are concerns and there is no clear use case then I for one would be happy to take it out again in which case BGPSec assertions can only be filtered on matching ASN.
