Post-Quantum Prep Without the Panic: Don’t Delay Your Upgrade to TLS 1.3

What if quantum computing feels years away, but your migration to post-quantum cryptography needs to start today? In this episode of Shielded we welcome Kevin Hilscher, Senior Director of Product Management at DigiCert.

Designing for Breakage: What Cybersecurity Leaders Must Plan For

In this episode of Shielded, we welcome Yolanda Reid, former IBM Consulting leader and U.S. defense veteran, to explain why PQC is not a patch, but a permanent shift in how we secure systems, train teams, and think about risk.

The Crypto Agility Paradox: When Hardware Becomes Your Security Bottleneck

In this episode of Shielded, we are joined by Cassie Crossley, Vice President of Supply Chain Security in the Global Cybersecurity & Product Security Office at Schneider Electric. Cassie shares the hard-earned lessons from a multi-year crypto agility program in one of the world’s largest OT environments.

From NIST Standards to Action: A Year of PQC Migration

In this special episode of Shielded, we revisit those early conversations about PQC migration to see how far we’ve come since the NIST standards were introduced a year ago.

Continuous Group-Key Agreement: Concurrent Updates without Pruning

Continuous Group Key Agreement (CGKA) is the primitive underlying secure group messaging. It allows a large group of N users to maintain a shared secret key that is frequently rotated by the group members in order to achieve forward secrecy and post compromise security.

Hardware Is the Hidden Risk: Ferhat Yaman on PQC, Side-Channel Attacks, and AI Privacy

We meet Ferhat Yaman, a security researcher at AMD’s Product Security Office, to explore the front lines of post-quantum cryptography, hardware vulnerabilities, and AI privacy.

Unmasking TRaccoon: A Lattice-Based Threshold Signature with An Efficient Identifiable Abort Protocol

In this work, we propose TRaccoon-IA, a TRaccoon with an efficient identifiable abort protocol, allowing to identify malicious signers when the signing protocol fails.

Comprehensive Deniability Analysis of Signal Handshake Protocols: X3DH, PQXDH to Fully Post-Quantum with Deniable Ring Signatures

We analyze Signal's classically secure X3DH and harvest-now-decrypt-later-secure PQXDH, and show the settings for which PQXDH is (un)deniable against harvest-now--later attacks..and more.

Exploring How to Authenticate Application Messages in MLS: More Efficient, Post-Quantum, and Anonymous Blocklistable

In this work, we focus on the authenticity of the application messages exchanged in MLS.

Bundled Authenticated Key Exchange: A Concrete Treatment of Signal’s Handshake Protocol and Post-Quantum Security

In this work, which was accepted at USENIX Security 2025, we propose a new way of modeling Signal handshake protocols.

The biggest risk to PQC migration is you (and other humans)

What if the biggest threat to your cybersecurity strategy isn’t quantum computing, but humans? In this episode of Shielded, we welcome Professor Bill Buchanan, OBE, FRSE, a global leader in applied cryptography, digital trust, and secure system design.

More Efficient Protocols for Post-Quantum Secure Messaging

More Efficient Protocols for Post-Quantum Secure Messaging is a talk presented by Thomas Prest at RWC 2024. This was the third talk in a session on post-quantum messaging, chaired by Dan Boneh.
