At deployment time, devices may not know the exact security groups to join, the respective Group Manager, or other information required to perform the joining process. This document describes how a CoAP endpoint can use descriptions and links of resources registered at the CoRE Resource Directory to discover security groups and to acquire information for joining them through the respective Group Manager. A given security group may protect multiple application groups, which are separately announced in the Resource Directory as sets of endpoints sharing a pool of resources. This approach is consistent with, but not limited to, the joining of security groups based on the ACE framework for Authentication and Authorization in constrained environments.

The IETF Secretariat --------------EAE310D3788B8A7929F0234E Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hello CoRE,

We have recently submitted an updated version of draft-tiloca-core-oscore-discovery

https://tools.ietf.org/html/draf= t-tiloca-core-oscore-discovery-08

The document describes how to use the CoRE Resource Directory for discovering OSCORE groups, by retrieving the link to join them through their Group Manager.

This update is especially about:

1) Adding target attributes related to the pairwise mode of Group OSCORE.

2) Considering also additional types of clients querying the RD, e.g. signature verifiers in Group OSCORE.

3) Using the content-format "application/ace-groupcomm+cbor" for the links to join OSCORE groups.

4) Fixes and improvements in the examples.


Comments are very welcome!

Best,
/Marco

Abstract:
Group communication over the Constrained Application Protocol (CoAP)
can be secured by means of Group Object Security for Constrained RESTful Environments (Group OSCORE). At deployment time, devices may
not know the exact security groups to join, the respective Group Manager, or other information required to perform the joining
process. This document describes how a CoAP endpoint can use
descriptions and links of resources registered at the CoRE Resource
Directory to discover security groups and to acquire information for
joining them through the respective Group Manager. A given security
group may protect multiple application groups, which are separately
announced in the Resource Directory as sets of endpoints sharing a<= br> pool of resources. This approach is consistent with, but not limited
to, the joining of security groups based on the ACE framework for Authentication and Authorization in constrained environments.



Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
