This document defines two CBOR Object Signing and Encryption (COSE)
header parameters for incorporating timestamping based on RFC 3161
into COSE message structures (COSE_Sign and COSE_Sign1). This enables
the use of established timestamping infrastructure per RFC 3161 in
COSE-based protocols.
This document is a product of the CBOR Object Signing and Encryption Working
Group of the IETF.
This is now a Proposed Standard.
