The End of Static Cryptography: What Leaders Must Understand Now

This special episode of Shielded brings together experts from cryptography, security architecture, and risk to explain what comes next. The conversation clarifies that security can no longer rely on fixed algorithms or one-time upgrades.

Confidentiality vs Authentication: How Far the Web Has Actually Moved

In this episode of Shielded Jo Lintzen speaks with Sofia Celi, Senior Cryptography and Security Researcher at Brave, co-author of the MAYO signature scheme, and co-chair of an IETF working group driving global PQC standards.

The Hidden Threat: Harvest-Now-Forge-Later and the Collapse of Digital Trust

In this episode of Shielded, Jo Lintzen speaks with Kevin Reifsteck, Director for Critical Infrastructure Protection at Microsoft, about how governments and global enterprises can turn quantum-safe readiness from policy into practice.

An Efficient and Generic Construction for Signal’s Handshake (X3DH): Post-quantum, State Leakage Secure, and Deniable

The Signal protocol is a secure instant messaging protocol that underlies the security of numerous applications such as WhatsApp, Skype, Facebook Messenger among many others.

Breaking Parallel ROS: Implication for Isogeny and Lattice-based Blind Signatures

In this work, we provide a simple and novel attack on blind signatures based on identification protocols performing parallel repetition to reduce the soundness error.

New Whitepaper: “The new NIST standards are here: what does it mean for PQC in 2025?”

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

CV2EC: Getting the Best of Both Worlds

Converting CryptoVerif models to EasyCrypt: getting the best of both worlds.

Adaptively Secure 5 Round Threshold Signatures from MLWE/MSIS and DL with Rewinding

T-out-of-N threshold signatures have recently seen a renewed interest, with various types now available, each offering different tradeoffs. However, one property that has remained elusive is adaptive security.

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.
