This document standardizes a use of PASSporTs, exercising its extension
mechanisms. Its intended status is Proposed Standard.

This document extends PASSporT, which is a token object that conveys
cryptographically-signed information about the participants involved
in communications, to include information defined as part of the
SHAKEN specification from ATIS (Alliance for Telecommunications
Industry Solutions) and the SIP Forum IP-NNI Joint Task Force. These
extensions provide a level of confidence in the correctness of the
originating identity for a telephone network that has communications
coming from both STIR participating originating communications as
well as communications that does not include STIR information.

The shepherd reviewed this document, ran id-nits, and visually inspected
the example PASSporTs provided.

This document began WGLC in April 2018. Feedback from the group was
minimal. (The document is short and straightforward.)
One suggestion to use the compact form of PASSporT with
these claims was discussed at the STIR session at IETF 102. The
suggestion was rejected (in offline conversations), and the document
was updated to explicitly state that the use of the compact form of
PASSporT is not specified. The security considerations section was
added to the document very late in the process, but again, the document
is short and straightforward, and the security considerations are not

There are no such concerns outstanding,

Each author has so confirmed.

There are no such disclosures filed.

The document is straighforward and has the consensus of the working
group, even if feedback has been minimal.

No such references exist, but the IESG should note the normative
reference to the the ATIS/SIP Forum NNI Task Group document at
[ATIS-10000074]. The group believes this normative reference is
