The biggest risk to PQC migration is you (and other humans)

What if the biggest threat to your cybersecurity strategy isn’t quantum computing, but humans? In this episode of Shielded, we welcome Professor Bill Buchanan, OBE, FRSE, a global leader in applied cryptography, digital trust, and secure system design.

The Crypto Agility Paradox: When Hardware Becomes Your Security Bottleneck

In this episode of Shielded, we are joined by Cassie Crossley, Vice President of Supply Chain Security in the Global Cybersecurity & Product Security Office at Schneider Electric. Cassie shares the hard-earned lessons from a multi-year crypto agility program in one of the world’s largest OT environments.

Your Hardware Refresh Is a Quantum Deadline with Mamta Gupta, Lattice Semiconductor

In this episode of Shielded, Johannes Lintzen sits down with Mamta Gupta of Lattice Semiconductor to explore how hardware-rooted security must evolve to meet the post-quantum challenge.

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.

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.
