🔐 Chrome is testing a new model of HTTPS certifications in preparation for the post-quantum era.
In a proactive step against the risks of quantum computing, Google Chrome is testing what’s known as Merkle Tree Certificates (MTCs) — a radically different mechanism than the traditional X.509 certification model.
The problem is clear: Integrating post-quantum signature algorithms within the X.509 series will result in a significant boom in certificate volume, meaning a significant increase in TLS handshake data and a direct impact on performance.
The suggested solution is based on the structure of Merkle Tree:
Instead of the credentialing book signing...
