About a), I don't think putting all the CA certs in the voucher is a good idea. EST should be used instead. I don’t think it is right for someone to expect the voucher to distribute its roots of trust. What if a CA cert gets revoked of expires? EST has the transitional certs that allow for root CA cert update, but I don't think we can expect someone to rerun BRSKI in order to get its new root of trust.
The cert chain in the voucher should only enable the client to establish a trust relationship with the server. So, I think only one root cert for the domain should be carried in the voucher. The rest of the certs in the chain of the server cert should be sent by the server in the TLS negotiation. About b), optimizing the cacerts response. The truth is that cacerts can grow a lot in size. The enroll response could also be big for constrained environments depending on algorithms used. Some thoughts have been proposed in pkix/tls in the past to shrink certs like caching and compression, but they have some disadvantages. DTLS also provides a fragmentation mechanism in the handshake to accommodate for large records (ca certs in this case). Thus optimizing the responses might not be necessary, or even easy for that matter. Let's say you still wanted to think about it. I don't think JWT or CBOR would add any shrinkage to an ASN.1 cert chain. Now if you are contemplating using a new free-form JSON certificate format (instead of CMS) and then using JWT or CBOR to secure and shrink it, I am not sure about size improvements. CMS' ASN.1 is not human friendly, but I would be interested if writing the cert fields in free-form JSON and encoding with CBOR/JWT would really lead to a shorter total size. In other words, I am not sure going beyond JSON vouchers/tokens when talking about new encodings (JWT, CBOR) is something we should tackle.

Yes: Enrollment over Secure Transport (EST) is *not* intended to be a new enrollment protocol (instead it focused on clarifying how simple CMC messages could be used when a secure transport is available). As such the /cacerts response is a CMC subset "PKCS#7 "certs-only” response”. That is a really heavy structure to deliver what is essentially, but not exactly, the JWT x5c certificate chain. :( > Doing JWS/COSE or JWT/CWT needs additional code. > I am sensitive to the payload size argument though. > > But, suppose the JWS or JWT is adopted to reduce the payload, where > will the optimizations stop? > Will you envisage to optimize the EST payloads as well? The EST discussion in the -06 concise draft is introduced as: "describes EST extensions necessary to enable fully automated bootstrapping”. It adds a couple of telemetry (success/fail messages) and mandates a few options that were defined in EST but has so far avoided redefining any EST messages. Thoughts: a) The voucher currently contains the x5c header necessary to deliver the CA certificate to move the existing TLS connection out of the provisional state — but this is not mandated to be the entire /cacerts chain. The client is instructed that: the domainCAcert is not a complete distribution of the EST section 4.1.3 CA Certificate Response. and The Pledge MUST request the full EST Distribution of CA Certificates message. See RFC7030, section 4.1. One approach is to ensure the voucher x5c header does contain everything necessary. This would allow a client that does not continue to use EST to have a full /cacerts equivalent response. Within BRSKI itself this would solve the discussion. We’re encroaching on redefining that header though (see RFC7515#section-4.1.6 where it x5c is defined — its a chain directly to the root without any cross certifications). If we include PKI /cacerts into there we need to change that definition via a new header type so that we can cover the oldwithnew, newwithold etc stuff from PKI land. b) Realistically any PKI client really “MUST” keep their ca certificates up to date. (BRSKI tries to frame this as optional to ensure a clean integration point for non-PKI type deployments). Therefore we could assume that /cacerts will be called and therefore embark on your point: an optimization of at least this EST payload. If we do take that path I’d lean toward a general purpose “discovery” document that details a bunch of information about the service including the x5c (or new form) header — thus making this a valuable addition and driving alignment toward the token concepts rather than just a new format. I’m worried about adding that but do see the value in that it allows a client to avoid any CMS/PKCS#7. Boy, either approach is redefining a message form that almost defined in a prior protocol. A great topic to hear folks on this list comment on. - max > > Cheerio, > > Peter > > > > Max Pritikin (pritikin) schreef op 2017-04-18 20:08: >> Folks, in Chicago we discussed the signing method for vouchers. >> Because the voucher is JSON, and there is expectation of a CBOR >> encoding for future work, there is an open discussion point about >> using the JWS/COSE signing methods; if not JWT/CWT.
