Google's PQC roadmap targets 2029 migration with Merkle Tree Certificates
Google has published a product-by-product roadmap for its post-quantum cryptography migration, moving its deadline to 2029 — six years ahead of NIST guidance. The plan centers on Merkle Tree Certificates from Google Trust Services in 2028, which replace bulky post-quantum signatures in X.509.
- Google moved its PQC migration deadline to 2029, six years ahead of NIST
- Google Trust Services will deploy Merkle Tree Certificates in 2028
- MTCs keep the X.509 format but replace signatures with a public log proof
- The IETF draft is authored by Google, Apple, Cloudflare and Geomys
