A Post-Quantum Future for Let's Encrypt
Let’s Encrypt is committed to a post-quantum-safe Web PKI. The path we’re planning to take is Merkle Tree Certificates (“MTCs”), a new approach that adds post-quantum authentication to the web without sacrificing the speed and reliability that have made TLS universal. This post is about these plans and why we believe MTCs are worth pursuing as a key to a post-quantum future. An increasingly urgent problem For much of the last several years, the conversation about post-quantum cryptography has been a conversation about encryption. The reasoning was straightforward: an attacker who records encrypted traffic today might be able to decrypt it years from now once quantum computers can break the underlying math. Authentication, the part of TLS that indicates a server is who it says it is, has been a less urgent problem. A quantum computer needs to forge a signature in real time, not retroactively, so threats to authentication hinge on the existence of a cryptographically relevant quantum computer (CRQC).

One benefit of a “proof of fidelity” system where you aren’t trying to solve for such a narrow question of “is this a human”, is that you don’t need to rely on means of validation that can be biased or inaccessible for many actual humans, such as gov IDs or irl events.2/x— 🌸 ellie 🌸 (@heyellieday) July 29, 2021
