Beyond Object Authentication: Context-Closed Post-Quantum Authentication for the WebPKI
New formal model shows that post-quantum WebPKI migration must preserve the mutable authorisation context around certificates, not just authenticate the certificate object—a gap current PQC transition plans may overlook.

arXiv:2608.30004v1 Announce Type: new Abstract: Post-quantum migration increases WebPKI authentication cost, but authenticating a compressed certificate object does not by itself preserve the mutable authorization context under which a relying party accepts it. We formalize \emph{context closure}: the authenticated projection accepted by a verifier must determine the selected authorization semantics it claims, relative to declared source contracts and event-coverage witnesses. We instantiate th
Editorial Analysis
Enterprises planning post-quantum TLS migration risk a false sense of security if certificate authentication ignores the broader authorisation context, potentially leaving revocation and policy decisions unprotected.
