Subject: [Rats] FW: New Version Notification for draft-tschofenig-rats-psa-token-05.txt

Dear all,

We have just published -05 of the PSA token draft.

This update is mostly cosmetic -- we have aligned the presentation
of the claims to that in the EAT draft, including CDDL.

The only relevant change (not at a semantic level) is that we now
allow (but not recommend) COSE Mac0 authentication.

Please have a look, and thank you in advance for any feedback.

Cheers!

    Abstract:
       The Platform Security Architecture (PSA) is a family of hardware and
       firmware security specifications, as well as open-source reference
       implementations, to help device makers and chip manufacturers build
       best-practice security into products.  Devices that are PSA compliant
       are able to produce attestation tokens as described in this memo,
       which are the basis for a number of different protocols, including
       secure provisioning and network access control.  This document
       specifies the PSA attestation token structure and semantics.

       At its core, the CWT (COSE Web Token) format is used and populated
       with a set of claims in a way similar to EAT (Entity Attestation
       Token).  This specification describes what claims are used by PSA
       compliant systems.

    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.
