Cloudflare adds post‑quantum signatures to origin pulls, locking down server‑to‑server links
Cloudflare’s Authenticated Origin Pulls and Custom Origin Trust Store now accept ML‑DSA post‑quantum signatures, enabling fully quantum‑resistant TLS authentication between Cloudflare edge nodes and customer origin servers. This thwarts future quantum impersonation attacks on the server‑to‑origin link, completing the first milestone of Cloudflare’s 2029 post‑quantum security roadmap.
