Our applied PQC series continues. This time, @k15ab_ and @6c656e69 attack masked Kyber768. Masking defeats first-order SCA. But with a centered cross-product and the right covariance model, a second-order CPA recovers the secret coefficient.

We continue our series on applied PQC. This time, a study of side-channel attacks on ML-KEM by @k15ab_ and Alain M. Math is the foundation, but in the real world, attackers have other tricks.
