The IESG has received a request from the CBOR Object Signing and
Encryption WG (cose) to consider the following document:
- 'CBOR Object Signing and Encryption (COSE)'
  <draft-ietf-cose-msg-18.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the mailing lists by 2016-09-28. Exceptionally, comments may be
sent to instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.


   Concise Binary Object Representation (CBOR) is data format designed
   for small code size and small message size.  There is a need for the
   ability to have basic security services defined for this data format.
   This document defines the CBOR Object Signing and Encryption (COSE)
   specification.  This specification describes how to create and
   process signature, message authentication codes and encryption using
   CBOR for serialization.  This specification additionally specifies
   how to represent cryptographic keys using CBOR.
