Re: [Ace] I-D Action: draft-ietf-ace-coap-est-11.txt

Thanks,

A few comments I had still on the discovery section - sorry to be late post-WGLC with this:

- page 10 bottom mentions "management data" - should say "management resources", or "EST resources" perhaps?
- page 10 bottom: " Upon success, the return payload will contain the root resource of the EST resources." - this is not true, since only the individual supported resources are returned. The root (e.g. "/est" in the examples) can be deduced from the response but it is never returned as one link format entry.
- page 11 top: the example is only correct for a secure (coaps://) discovery GET request, I think this could be mentioned in text or indicated in the request line.
- page 11 bottom requirement: " The client SHOULD use resource discovery when he is unaware of the available  EST-coaps resources." - when an EST server is known, this requirement does not really apply since the server always supports .well-known EST resources.  So I read it as doing an RD discovery or multicast CoAP discovery if the client doesn't known the EST server address.  Hope this is clear enough in the text and intended?
- page 11 bottom: "he supports" -> "it supports"
- page 11 bottom: " It is up to the implementation to choose its resource paths” -> seems not really the case, because the root resource structure is forced by the specification. It could have been designed as free choice (because it can be discovered anyway) but it is not.

Best regards
Esko

Hi all, 

This latest update addresses feedback while in WGLC" 
- the comments by Hannes and Esko related to RNG and server-side key gen. It aims to prevent misunderstandings that random numbers are not needed any more if server-side key gen is used. 
- the nits with "/crt" instead of "/crts" pointed out by Esko.

Thanks,
Panos

Abstract:
   Enrollment over Secure Transport (EST) is used as a certificate
   provisioning protocol over HTTPS.  Low-resource devices often use the
   lightweight Constrained Application Protocol (CoAP) for message
   exchanges.  This document defines how to transport EST payloads over
   secure CoAP (EST-coaps), which allows constrained devices to use
   existing EST functionality for provisioning certificates.
