Cloudflare's development of Merkle Tree Certificates offers a critical architectural shift for post-quantum cryptography, addressing the scalability bottleneck where traditional signature sizes would overwhelm Certificate Transparency logs. By integrating transparency directly into the issuance process via an append-only tree structure, this approach ensures that quantum-safe TLS handshakes remain efficient without sacrificing the rigorous auditing required by browsers like Chrome. This initiative represents a significant step forward in making practical, high-performance quantum-resistant web authentication feasible for global infrastructure.

Cloudflare Builds Post-Quantum CA With Merkle Tree Certificates for Faster Quantum-Safe TLS

Cybersecurity News4 min read

Cloudflare is building a certificate authority to make post-quantum website authentication practical without burdening TLS connections with oversized signatures. The company plans to issue conventional certificates alongside Merkle Tree Certificates, or MTCs, and is targeting early 2027 for admission to Chrome’s new Quantum-resistant Root Store; standard MTC issuance will be free. The initiative addresses a […] The post Cloudflare Builds Post-Quantum CA With Merkle Tree Certificates for Faster Quantum-Safe TLS appeared first on Cyber Security News.
