Please note the publication of Draft 13 of the EAT document.  This is the version that is intended to be distributed for IESG review, and the editors request the chairs to do so no later than May 25.  Note the following changes:

-	Clarification on use of the eat-nonce rather than the currently registered JWT-nonce.  The JWT-nonce has restrictions on use as defined and is not suitable for general use in attestation.
-	Revised text on the security level claim, including reduction to 3 levels
-	Grouping of claim definitions to those specific to the entity and those specific to the token
-	Removal of normative references to UCCS as per Working Group consensus direction provided at IETF 113
-	Modification of measurement results claim

Further discussion on changes can be found in Section E.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Remote ATtestation ProcedureS WG of the IETF.

        Title           : The Entity Attestation Token (EAT)

                          Giridhar Mandyam

Abstract:
   An Entity Attestation Token (EAT) provides an attested claims set
   that describes state and characteristics of an entity, a device like
   a phone, IoT device, network equipment or such.  This claims set is
   used by a relying party, server or service to determine how much it
   wishes to trust the entity.

   An EAT is either a CBOR Web Token (CWT) or JSON Web Token (JWT) with
   attestation-oriented claims.  To a large degree, all this document
   does is extend CWT and JWT.
