Exploiting Small-Norm Polynomial Multiplication with Physical Attacks [PDF]

Transactions on Cryptographic Hardware and Embedded Systems
We present a set of physical profiled attacks against CRYSTALS-Dilithium that accumulate noisy knowledge on secret keys over multiple signatures, finally leading to a full key recovery attack. The methodology is composed of two steps.
