Pre-processing power traces to defeat random clocking countermeasures

2015

We describe a pre-processing correlation attack on an FPGA implementation of AES, protected with a random clocking countermeasure that exhibits complex variations in both the location and amplitude of the power consumption patterns of the …

Lattice-based Encryption Over Standard Lattices In Hardware

2016

Lattice-based cryptography has gained credence recently as a replacement for current public-key cryptosystems, due to its quantum-resilience, versatility, and relatively low key sizes. To date, encryption based on the learning with errors (LWE) problem has …

A Highly Hardware Efficient ML-KEM Accelerator with Optimised Architectural Layers

2024 · ACM Transactions on Embedded Computing Systems

The Module-Lattice-Based Key encapsulation Mechanism (ML-KEM) scheme, which is currently being standardised, is a quantum attack resistant KEM that is based on CRYSTALS-Kyber. CRYSTALS-Kyber is the only Public-key Encryption (PKE)/ KEM scheme selected in the …
