Ballot Text

Technical Summary

   This document defines a CBOR Signing And Encrypted (COSE) header
   parameter for incorporating RFC 3161-based timestamping into COSE
   message structures (COSE_Sign and COSE_Sign1).  This enables the use
   of established RFC 3161 timestamping infrastructure to prove the
   creation time of a message.
