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.

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).

Today Letsencrypt announced their plans for PQC migration and, oh boy, it's refreshing! TL;DR, Letsencrypt considers migration to quantum-resistant certificates a priority, and lays down a reasonable path to migrate. In so doing, they take the time to explain how, so far, the security community has been mainly focused on the problem of quantum-resistant secrecy (encryption) rather than authentication (signatures/certificates), and they explain why the sentiment is changing now, and why it is particularly relevant for Letsencrypt.

Not wanting to be the "told you so" guy, I've been saying this for at least 2 years now:

This is not to say that Harvest-Now-Decrypt-Later is a less urgent threat, but it's not as asymmetric as people have been believing so far. Glad to see things are changing!

🚀 Ah, the elusive post-quantum world where #encryption is meaningless and Let's Encrypt pretends to be relevant. 😂 Who knew a page full of language options could be more exciting than the actual content? 🌍

We're starting our webinar on Physical Attacks on PQC Implementations 📢

Join the talk: https://zoom.us/meeting/register/NIX4FovvREe3n6KJ2JbrqA#/registration
#pqc #postquantum #postquantumcryptography

Welcome! You are invited to join a meeting: Securing Post-Quantum Implementations Against Physical Attacks. After registering, you will receive a confirmation email about joining the meeting.

Quantum-resistant algorithms are arriving in real devices;  but physical attacks may already undermine them. eShard and PQShield explore whether side-channel and fault injection attacks pose a real-world threat to PQC implementations, with a live walkthrough of a CPA attack on ML-KEM and first-step countermeasures. Speakers: → Dr Rafael Carrera Rodriguez, Hardware Security Analyst, eShard → Dr Adrian Thillard, Principal Security Analyst, PQShield (ex-Ledger Donjon, ex-ANSSI) Live, interactive session. Limited capacity.  By registering you agree to eShard's Privacy Policy: https://www.eshard.com/privacy-policy
