Today marks a massive milestone for Japan’s digital sovereignty. Following PQShield’s comprehensive evaluation of the ML-KEM algorithm for CRYPTREC (Japan’s cryptographic standardization body), the gates are officially open for quantum-safe deployment across the country’s government procurement and technology supply chains.

This paper details how to protect FrodoKEM against physical side-channel attempts. The authors provide a new, protected implementation for embedded chips and use hardware testing to prove it successfully thwarts these real-world attacks.

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.

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.

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.

This Brief explains how PQShield delivers DPA-protected solutions to defend long-lived PQC secrets against physical attacks. PQMicroLib-Core Edge Grade is designed for exposed, embedded environments. Read more.

In this episode of Shielded, Jo Lintzen speaks with two experts at Mobile World Conference in Barcelona. Amidst the buzz of the industry being in one place, they discuss the security landscape in the AI era.

In this episode of Shielded we speak with Stefan Kölbl, an information security engineer at Google, about what it actually takes to migrate cryptography across complex global systems at scale.

This is paper is concerned with the theoretical basis of lattice-based cryptography, clarifying how “easy” distinguishing attacks relate to “hard” search attacks used in security proofs.

In this episode of Shielded, Jo speaks to Darren Bender, a US litigation attorney and Chief Litigation Officer in the post-quantum cryptography sector.

In this paper, we present a simpler, more efficient way to create a secure, quantum-resistant shared "vault" (a threshold KEM) without using overly complex or slow mathematical tools. It's achieved by combining established cryptographic frameworks with a new, proven mathematical assumption called Coset-Hint-MLWE. The result is a highly secure system that is easier to implement and more practical for real-world use than previous versions.
