SPOTLIGHT PUBLICATION | 14/08/2024

New Whitepaper: “The new NIST standards are here: what does it mean for PQC in 2024?”

Yesterday NIST published their finalized post-quantum cryptography (PQC) standards. This paper discusses the standards in more detail and what comes next.

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.

Filter by:

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.

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.

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.

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.

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.

Fully Adaptive Schnorr Threshold Signatures

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

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.
