In this latest collaboration with eShard, we review a significant side-channel vulnerability in lattice-based implementations, as discovered earlier this year by Tolun Tosun, Amir Moradi, and Erkay Savas.
The research describes the leveraging of many implementations, particularly ML-KEM and ML-DSA, to mount a side-channel attack that works around masking countermeasures.This ongoing series continues our detailed look at side-channel masked implementations, and highlights the importance of understanding the security of these techniques.
With the NIST standards expected to be widely adopted later this year, the impact of this work is likely to be felt in the immediate future.
