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.

Cryptography Modernization Part 1: Where is your Cryptography?

A plain english guide to help you get ready to comply with the new cryptography standards.

Signature for Objects: Formalizing How to Authenticate Physical Data and More

This paper proposes a new concept called signatures for objects to guarantee the integrity of objects cryptographically.

A Key-Recovery Attack Against Mitaka in the t-Probing Model

We uncover a flaw in the security proof of MITAKA, and subsequently show that it is not secure in the t-probing model.

Zero-Knowledge Arguments for Subverted RSA Groups

This work investigates zero-knowledge protocols in subverted RSA groups where the prover can choose the modulus and where the verifier does not know the group order.

Area–Time Efficient Implementation of NIST Lightweight Hash Functions Targeting IoT Applications

This work presents field-programmable gate array (FPGA) implementations and carefully worked out optimizations of four Round-3 finalists in the NIST standardization process

A 334 μW 0.158 mm² ASIC for Post-Quantum Key-Encapsulation Mechanism Saber With Low-Latency Striding Toom–Cook Multiplication

We demonstrate that a memory-efficient striding Toom–Cook with lazy interpolation results in a highly compact, low-power implementation, which, on top, enables a very regular memory access scheme.

Comparing Key Rank Estimation Methods

Recent works on key rank estimation methods claim that algorithmic key rank estimation is too slow, and suggest two new ideas.

RISC-V Instruction Set Extensions for Lightweight Symmetric Cryptography

The NIST LightWeight Cryptography (LWC) selection process aims to standardise cryptographic functionality which is suitable for resource-constrained devices.

How to Hide MetaData in MLS-Like Secure Group Messaging: Simple, Modular, and Post-Quantum

Secure group messaging (SGM) protocols allow large groups of users to communicate in a secure and asynchronous manner.

A New Framework for More Efficient Round-Optimal Lattice-Based (Partially) Blind Signature via Trapdoor Sampling

Blind signatures, proposed by Chaum (CRYPTO’82), are interactive protocols between a signer and a user, where a user can obtain a signature without revealing the message to be signed.

Secure Messaging in a Post-Quantum World

Team PQShield experts outline how PQC can be applied to secure messaging in a two-party setting, typically between mobile devices, as well as the specific performance and data requirements.

WiP: Applicability of ISO Standard Side-Channel Leakage Tests to NIST Post-Quantum Cryptography

We discuss how to apply ISO 17825 to hardware modules that implement lattice-based PQC standards for public-key cryptography. We find that simple “random key” vs. “fixed key” tests are unsatisfactory due to the close linkage between public and private components of PQC keypairs.
