PQC vs. QKD: What Matters Now and What Can Wait

In this episode of Shielded, we talk with Will Collison, Interim Global Head of Cryptography at HSBC. Will explains how to separate PQC, QKD, and quantum computing, and why cryptographic agility is the real objective.

3, 5 or 8 Years? The Realistic Timeline for Migration and the Task That Can’t Wait

What if quantum computing feels like a distant threat, but your timeline to prepare is already running out? We welcome Adrian Neal, Senior Director and Global Lead for Post-Quantum Cryptography at Capgemini.

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.

On Entropy and Bit Patterns of Ring Oscillator Jitter

We show how to evaluate entropy, autocorrelation, and bit pattern distributions of thermal jitter ring oscillator noise sources, even with low jitter levels or some bias.

Development of the RISC-V entropy source interface

The RISC-V true random number generator (TRNG) architecture breaks with previous ISA TRNG practice by splitting the entropy source (ES) component away from cryptographic DRBGs.

MIRACLE: MIcRo-ArChitectural Leakage Evaluation: A study of micro-architectural power leakage across many devices

In this paper, we describe an extensible experimental infrastructure for evaluating the micro-architectural leakage, based on power consumption, that stems from a physical device.

A Concrete Treatment of Efficient Continuous Group Key Agreement via Multi-Recipient PKEs

Continuous group key agreements (CGKAs) are a class of protocols that can provide strong security guarantees to secure group messaging protocols such as Signal and MLS.

A lightweight ISE for ChaCha on RISC-V

This paper proposes a lightweight ISE to support the cipher ChaCha on RISC-V architectures. we target embedded computing systems such as IoT edge devices that don’t support a vector engine.

XDIVINSA: eXtended DIVersifying INStruction Agent to Mitigate Power Side-Channel Leakage

Side-channel analysis (SCA) attacks pose a major threat to embedded systems due to their ease of accessibility.

An Instruction Set Extension to Support Software-Based Masking

In both hardware and software, masking can represent an effective means of hardening an implementation against side-channel attack vectors such as Differential Power Analysis (DPA).

Probing Security through Input-Output Separation and Revisited Quasilinear Masking

This paper introduces a new framework for the composition of probing-secure circuits.

SoK: How (not) to Design and Implement Post-quantum Cryptography

Post-quantum cryptography has known a Cambrian explosion in the last decade. We systematize the current state of knowledge on post-quantum cryptography.

Exact Lattice Sampling from Non-Gaussian Distributions

We propose a new framework for (trapdoor) sampling over lattices.

Exploring Parallelism to Improve the Performance of FrodoKEM in Hardware

FrodoKEM is a lattice-based key encapsulation mechanism, currently a semi-finalist in NIST’s post-quantum standardisation effort.

Quantum Computing Threat: NIST PQC standards are here… how can you keep ahead?

Cryptographic agility and a clear roadmap to the NIST standards are key to a smooth and secure transition to PQC.
