Cloudflare Plans Public Certificate Authority for Post-Quantum Security
Cloudflare has announced plans to launch a public Certificate Authority that supports both traditional encryption and post-quantum Merkle Tree Certificates. The initiative aims to secure the internet against future quantum computing threats while maintaining compatibility with older devices.
Why it matters
As quantum computing advances, current encryption standards face obsolescence; this move provides a proactive infrastructure upgrade for global web security.
PRESS RELEASE — Cloudflare, Inc. (NYSE: NET), the leading connectivity cloud company, today announced its intent to become a public Certificate Authority (CA), an open service that issues the digital certificates websites need to encrypt traffic and prove their identity to visitors. The new CA will support both traditional encryption and next-generation post-quantum Merkle Tree Certificates (MTCs), giving every website a path to stay protected as computing power advances—with no new tools or rebuilds required. Additionally, Cloudflare has agreed to acquire established, publicly trusted Root CA key material from GlobalSign, which will provide ubiquity across the global Web PKI ecosystem.
