Global Standards, Regional Variants: Designing for PQC Across Jurisdictions

In this episode of Shielded, Jo Lintzen speaks with Dr. Richard Searle, Chief AI Officer at Fortanix, about how confidential computing and a software-first model accelerate the shift to post-quantum cryptography.

Solution brief: PQShield and Quantum Origin strengthening post-quantum cryptography with proven quantum randomness
PQShield and Quantinuum have developed a joint solution, combining Quantum Origin’s mathematically-proven Quantum Random Number Generation (QRNG) with PQShield’s FIPS-140-3-validated post-quantum cryptographic library in PQCryptoLib-SDK, for resilient post-quantum algorithms.

No-Regrets Migration: Why PKI Should Be Your First Move
In this episode of Shielded, Johannes Lintzen speaks with Bruno Couillard, CEO and co-founder of Crypto4a, about his journey from designing the original Luna HSM to building the next generation of quantum-safe hardware.

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.

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.

TLS → Post-Quantum TLS: Inspecting the TLS landscape for PQC adoption on Android
We need to better understand the constraints and requirements of TLS usage by Android apps in order to make an informed decision for migration to the post-quantum world.

High-Order Masking of Lattice Signatures in Quasilinear Time
We design a lattice-based signature scheme specifically for side-channel resistance and optimize the masked efficiency as a function of the number of shares.

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.
