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.

HSMs and PQC Migration: Are We There Yet? / RSA
In this special RSA 2025 edition we gather 4 leading voices from the world of hardware security to discuss a cornerstone technology powering the post-quantum migration: the Hardware Security Module (HSM).

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.

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.

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.

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.
