Real-world post-quantum TLS
06-18, 10:15–11:15 (America/New_York), Great Falls

Quantum computers are coming which may break the security of existing TLS communications. Therefore we need post-quantum (PQ) cryptography to secure the new world. In this session, we will go over the basic flow of a TLS session, and compare various configurations (TLS 1.2, TLS 1.3, TLS 1.3 with PQ). We will also discuss how we can use Wireshark to study real-world traffic on the public Internet. Since TLS is encrypted, we will also go over methods to enable TLS decryption.

Peter Wu is part of the Research Team at Cloudflare, working on various TLS and cryptography-related projects. He is a contributor to many open source projects, including Wireshark, where he started in 2013 with TLS decryption improvements in order to assist in analyzing encrypted application traffic. Peter added TLS 1.3, QUIC, and WireGuard decryption support to Wireshark and aims to help everyone understand their traces.
