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.

Your Hardware Refresh Is a Quantum Deadline with Mamta Gupta, Lattice Semiconductor

In this episode of Shielded, Johannes Lintzen sits down with Mamta Gupta of Lattice Semiconductor to explore how hardware-rooted security must evolve to meet the post-quantum challenge.

HSMs and PQC Migration: Are We There Yet? / RSA

In this special RSA 2025 edition we gather 4 leading voices from the world of hardware security to discuss a cornerstone technology powering the post-quantum migration: the Hardware Security Module (HSM).

Flood and submerse: Distributed Key Generation and Robust Threshold Signature from Lattices

We propose a new framework based on random submersions for constructing verifiable short secret sharing and showcase it to construct efficient threshold lattice-based signatures in the hash-and-sign paradigm, when based on noise flooding.

Two-Round Threshold Signature from Algebraic One-More Learning with Errors

In this work, we construct the first efficient two-round lattice-based threshold signature without relying on FHE or HTDC.

CSI-Otter: Isogeny-based (Partially) Blind Signatures from the Class Group Action with a Twist

In this paper, we construct the first provably-secure isogeny-based (partially) blind signature scheme. (journal version)

Post-Quantum Secure Boot for Processors and FPGAs

This whitepaper summarises the current state of the PQC standards and the governmental regulations. It especially highlights the US Commercial National Security Algorithm Suite (CNSA) 2.0 which mandates software/firmware1 signing to use quantum-safe signatures as the default option by 2025, and as the only option by 2030.

Formally verifying Kyber Episode V: Machine-checked IND-CCA security and correctness of ML-KEM in EasyCrypt

Using computer-assisted proof tools to ensure security and correctness of Kyber and NIST-standard ML-KEM.

Post-Quantum Cryptography for Defence and Governmental Applications: Overview and Use Cases

Protecting the Military against the Quantum Threat to Today’s Cryptography.

Side-channel analysis: why it matters?

Side-channel attacks are a physical type of threat that aims to recover sensitive data manipulated by your code without using cryptanalysis, or taking advantage of software vulnerabilities.

Pioneering Side Channel Resistance for PQC

PQShield enables their customers to de-risk their development process with a comprehensive security strategy, rooted in the expertise of its world-class R&D team.

Securing telecommunications networks against the quantum threat

In the near future, it's likely that the development of quantum computers will pose a significant threat to the methods that currently keep online information secure.

Cryptography Modernization Part 2: Crypto-agility and hybrid schemes

In this second part to our no-nonsense guide on cryptographic modernization, our experts explore the topic of crypto-agility.

The Three Body Problem: There’s more to building Silicon than what EDA tools currently help with

Electronic Design Automation (EDA) tooling facilitates the development of cutting edge technologies at the nanometre scale.

On Gaussian sampling, smoothing parameter and application to signatures

We present a general framework for polynomial-time lattice Gaussian sampling. Using our techniques, we gain around 200 bytes (>20%) on the signature size.
