Episode 2: The Quantum-Safe Playbook: How Signal Protected Billions with a Lean Team

Quantum risk is a business risk—and Signal Messenger isn’t waiting for quantum computers to arrive. In this episode of Shielded: The Last Line of Cyber Defense, Johannes Lintzen welcomes Rolfe Schmidt, Research Engineer at Signal Messenger, to explore how one of the world's most privacy-focused messaging platforms implemented post-quantum cryptography—even with a lean team.

Formal Verification – why does it matter for PQC?

Formal verification has become increasingly important in the realm of cryptographic primitives, which serve as the foundational elements of secure communication systems. As cryptographic algorithms underpin the confidentiality, integrity, and authenticity of digital information, any flaw in their implementation can lead to catastrophic security breaches.

Episode 1: Inside Cloudflare’s Post-Quantum Journey: Bas Westerbaan on Real-World Implementation

Is your organization truly prepared for the post-quantum era? In the premier episode of Shielded: The Last Line of Cyber Defense, host Johannes Lintzen is joined by Bas Westerbaan, Research Engineer at Cloudflare, to discuss why organizations must act now on post-quantum cryptography, how to navigate the two-phase migration process, and how to overcome key management, compliance, and performance challenges.

The Financial Market’s Transition to Post-Quantum Cryptography

This whitepaper, in conjunction with Quant-X, summarizes the current state of the PQC standards and the governmental regulations, outlines generic financial market specific threats that can be mitigated by post-quantum cryptography.

Efficient Boolean-to-Arithmetic Mask Conversion in Hardware

Masking schemes are key in thwarting side-channel attacks due to their robust theoretical foundation. Transitioning from Boolean to arithmetic (B2A) masking is a necessary step in various cryptography schemes.

High-Performance NTT Hardware Accelerator to Support ML-KEM and ML-DSA

This work presents a novel architecture of a high-performance NTT accelerator capable of performing both NTT and inverse NTT operations using a single set of hardware resources.

Video 1 – Algorithims are just recipes

The release of the new NIST standards is a great achievement but as Ali and Ben discuss in this recent video, algorithms are really only recipes – the key is how you use them.

Video 2 – NIST standards – the PQC turning point

In this video, Ben and Ali celebrate the publication of the first NIST PQC Standards. It’s a terrific achievement and a success for the whole collaborative PQC community.

Video 3 – How to think crypto agile

In this video, Ali and Ben talk about the way we each think about our business, and how that impacts decisions we make when it comes to protecting it – how can we deploy solutions that are able to change? What level of risk is acceptable?

Video 4 – Celebrating the cryptography community

In this clip, Ben and Ali reflect on the origins of PQShield as part of the wider cryptographic community and explain how great it is to be part of a community of unquestionably brilliant but genuinely down-to-earth cryptographers.
