Cloudflare plans to launch a free public Certificate Authority using Merkle Tree Certificates to mitigate the large payload size of post-quantum signatures in TLS handshakes. This initiative aims to facilitate a smooth transition to NIST standard algorithms, with public issuance expected by early 2027.

    • Uses Merkle Tree Certificates (MTC) instead of traditional X.509 chains to significantly reduce post-quantum TLS handshake overhead.
    • Mitigates TCP segmentation and latency caused by the large signature sizes of NIST-standard algorithms like ML-DSA and Falcon.
    • Public issuance scheduled for early 2027; requires pre-audit of client compatibility and automated certificate managers.
