Mapping the Supply Chain: A Faster Path to Organizational Resilience

In this episode of Shielded, Jo Lintzen speaks to Sarah McCarthy, Quantum Readiness Program Lead at Citi, who shares how Citi's quantum readiness program has evolved since 2022. They discuss supply chain readiness, and why the first step toward quantum safety does not require a dedicated team or advanced algorithms.

Solution Brief: PQMicroLib-Core for PQC Secure Boot in less than 5 KB of RAM

This Brief explains how PQShield PQMicroLib-Core enables a pure-software, OTA-deployable transition to Post-Quantum Secure Boot. PQShield’s ultra-small cryptographic library, PQMicroLib-Core is specifically designed to add quantum resilience to early boot and ROM stages. Read more.

Solution Brief: Drop-in Post-Quantum TLS for embedded devices with PQMicroLib-Core

This Brief explains how PQShield delivers a standards-based drop-in PQC TLS stack built on PQMicroLib-Core (PQC algorithms), PSA Crypto APIs (portable and interoperable abstraction) and MbedTLS (TLS protocol layer and certificate management). Read more.

Plover: Masking-Friendly Hash-and-Sign Lattice Signatures

We introduce a toolkit for transforming lattice-based hash-and-sign signature schemes into masking-friendly signatures secure in the t-probing mod

Threshold Raccoon: Practical Threshold Signatures from Standard Lattice Assumptions

Threshold signatures improve both availability and security of digital signatures by splitting the signing key into N shares handed out to different parties.

Raccoon: A Masking-Friendly Signature Proven in the Probing Model

This paper presents Raccoon, a lattice-based signature scheme submitted to the NIST 2022 call for additional post-quantum signatures.

How Multi-Recipient KEMs can help the Deployment of Post-Quantum Cryptography

The main purpose of this work is to raise awareness about a primitive that can provide large efficiency gains in post-quantum cryptography: multi-recipient KEMs, ormKEMs.

Optimizations and Practicality of High-Security CSIDH

In this work, we assess the real-world practicality of CSIDH, an isogeny-based non-interactive key exchange.

Practical Round-Optimal Blind Signatures in the ROM from Standard Assumptions

In this work, we present two round-optimal blind signatures under standard assumptions in the ROM with different approaches: one achieves the smallest sum of the signature and communication sizes, while the other achieves the smallest signature size.

Antrag: Annular NTRU trapdoor generation

In this paper, we introduce a novel trapdoor generation technique for Prest's hybrid sampler over NTRU lattices.

Cryptanalysis of the Peregrine Lattice-Based Signature Scheme

In this paper, we show that Peregrine, one of the candidates in the ongoing Korean post-quantum cryptography competition, is no exception, by demonstrating a practical key recovery attack against it.

An Improved Threshold Homomorphic Cryptosystem Based on Class Groups

We present distributed key generation and decryption protocols for an additively homomorphic cryptosystem based on class groups, improving on a similar system proposed by Braun, Damgård, and Orlandi at CRYPTO '23.

Mask Compression: High-Order Masking on Memory-Constrained Devices

In this work, we introduce mask compression. This conceptually simple technique is based on standard, non-masked symmetric cryptography.

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.
