   Title:   Kernel Identity and Attestation for Governing Enforcement Components

Abstract:

   This document specifies the Kernel Identity and Attestation (KIA)
   protocol for the Sovereign Object OS (SOOS) governance architecture.
   KIA defines the cryptographic identity of the GEC, the trust
   chain anchoring kernel authority from hardware root through operator
   root keypair to every signed Event Log entry, the GEC Manifest
   schema for runtime state attestation, and the Revocation Registry
   maintenance requirements.  KIA is the Layer 0 signing and
   attestation component on which the audit trail guarantees of
   draft-sato-soos-gar, the mandate enforcement guarantees of
   draft-sato-soos-mjwt, and the multi-agent delegation chain of
   draft-sato-soos-mad all depend.

   Version -03 adds FROST threshold signing for high-availability GEC
   keypair deployments, the Cross-Principal Identifier (XPID) for
   cross-instance federation audit correlation, the XPID cross-
   instance trust model, and four new Security Considerations
   (Sections 14.8 through 14.11) addressing FROST nonce reuse, XPID
   revocation gap, identity takeover via claimed identifier (CVE-2025-
   13609 class), and attestation channel binding (CVE-2026-33697 class).

   This document is the reference specification for the KIA RATS WG
   presentation at IETF 126 Vienna.  The XPID primitive and the
   CVE-2026-33697 attestation channel binding defense are the primary
   novel contributions presented to the RATS WG.

   Version -04 corrects a registry-format mismatch identified by IANA
   early review (#1456067): the Section 16 request to register
   XPID_DERIVED and XPID_VERIFICATION_FAILED into the GAR Authority
   Lifecycle Event Types Registry [I-D.sato-soos-gar] now uses that
   registry's actual column set (Event Type, Class, Reference) and
   assigns both entries the newly-defined Class ID (Identity/
   Federation event).  No new event types, fields, or normative
   behavior are introduced in -04; this is a registration-format
   correction only.
