Quantum Secure Key Management: PQShield and Cryptomathic’s CrystalKey360

This joint Guide with Cryptomathic outlines the critical challenges driving a major evolution in cryptographic key management, namely the threat of quantum computing and the growing complexity of multi-cloud environments

Complacency, Not Quantum, Is the Real Threat: Mike Silverman on Why Crypto-Agility Can’t Wait

In this episode of Shielded: Jo speaks to Mike Silverman, Chief Strategy & Innovation Officer at FS-ISAC. Mike shares why treating cryptographic migrations as one-off projects leaves organisations exposed, how building inventories and risk-based models creates real readiness, and why crypto-agility, not quantum anxiety, is the foundation for long-term security.

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.

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.

WrapQ: Side-Channel Secure Key Management for Post-quantum Cryptography

In this work, we study key handling techniques used in real-life secure Kyber and Dilithium hardware. We describe WrapQ, a masking-friendly key-wrapping mechanism designed for lattice cryptography.

Bingo: Adaptivity and Asynchrony in Verifiable Secret Sharing and Distributed Key Generation

We present Bingo, an adaptively secure and optimally resilient packed asynchronous verifiable secret sharing (PAVSS) protocol.

Fully Adaptive Schnorr Threshold Signatures

We prove adaptive security of a simple three-round threshold Schnorr signature scheme, which we call Sparkle+.

Snowblind: A Threshold Blind Signature in Pairing-Free Groups

Both threshold and blind signatures have, individually, received a considerable amount of attention. However little is known about their combination.

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.

Finding Short Integer Solutions When the Modulus Is Small

We present cryptanalysis of the inhomogenous short integer solution problem for anomalously small moduli q by exploiting the geometry of BKZ reduced bases of q-ary lattices.

TLS → Post-Quantum TLS: Inspecting the TLS landscape for PQC adoption on Android

We need to better understand the constraints and requirements of TLS usage by Android apps in order to make an informed decision for migration to the post-quantum world.
