Our Head of Research Thomas Prest will be speaking at CASCADE 2025 on – Masking-Friendly Lattice Schemes and Lattice-Friendly Masking Schemes.
“Masking is the most common countermeasure to protect cryptosystems against side-channel attacks. Unfortunately, lattice cryptosystems such as the recent NIST standards ML-DSA and ML-KEM are difficult to mask efficiently, resulting in poor performance when masked.
What happens when we incorporate masking-friendliness as a design criteria? In this talk, I will discuss how this methodology can lead to lattice cryptosystems that can be masked extremely efficiently – I will illustrate this point with the Raccoon signature scheme.
Conversely, masking schemes can be adapted to fit the quirks of lattice cryptosystems – I will illustrate this will a technique called “mask compression” which allows to implement masked lattice cryptosystems on memory-constrained devices.”
Thomas’s session will be on Thursday 4th April, 11:10 – 12:10.
