Cloudflare Develops Public Certificate Authority for Post-Quantum Web Security
InfoQ · By Leela Kumili ·
The Brief
- Cloudflare is developing a public certificate authority for Merkle Tree Certificates (MTCs).
- MTCs aim to reduce the bandwidth overhead of post-quantum cryptography in web certificates.
- A Chrome experiment served billions of MTCs to 50% of Chrome Beta 146 for selected domains, reporting a 9% faster median connection time.
Why it matters
Post-quantum certificates are much larger than current ones, and MTCs could cut the handshake overhead that slows down secure connections. A public CA would make this approach usable beyond Cloudflare's own infrastructure.
Who’s affected
- Website and API operators planning post-quantum TLS
- Teams running TLS certificate infrastructure
- Chrome Beta 146
