Internet-Draft draft-hardt-httpbis-signature-key-05.txt is now available. It
is a work item of the HTTP (HTTPBIS) WG of the IETF.
Title: HTTP Signature Keys

Abstract:
This document defines two HTTP header fields and one Accept-Signature
parameter for use with HTTP Message Signatures as defined in RFC
9421. The Signature-Key request header distributes public keys used
to verify signatures, with five initial key distribution schemes:
pseudonymous inline keys (hwk), self-issued key delegation via JWK
Thumbprint JWTs (jkt-jwt), identified signers with JWKS URI discovery
(jwks_uri), JWT-based delegation (jwt), and X.509 certificate chains
(x509). The sigkey parameter extends Accept-Signature (RFC 9421
Section 5) to indicate the type of Signature-Key the server requires.
The Signature-Error response header provides structured error
information when signature verification fails. Together, these
mechanisms enable flexible trust models ranging from privacy-
preserving pseudonymous verification to horizontally-scalable
delegated authentication and PKI-based identity chains.
