### AI overview

Cloudflare plans to become a public certificate authority and issue Merkle Tree Certificates designed to address the size of post-quantum signatures. The certificates use lightweight proofs tied to a trusted public log, and Cloudflare says its joint experiment with Google's Chrome team succeeded. To support older devices, Cloudflare plans to acquire an established root certificate they already recognize; the announcement did not identify the root or its owner.

### Source excerpt

Cloudflare Inc. today announced plans to become a public certificate authority that will offer certificates designed for the point when quantum computers can break current encryption. The new authority will issue a post-quantum format called Merkle Tree Certificates from the same system as conventional ones. The format is aimed at a size problem in post-quantum [...] The post Cloudflare to become a public certificate authority with post-quantum certificates appeared first on SiliconANGLE.
