In this work, we examine widespread components of various Post-Quantum Cryptography (PQC) schemes that exhibit disproportionately high overhead when implemented in software in a side-channel secure manner: fixed-weight polynomial sampling, Cumulative Distribution Table (CDT) sampling, and rotation of polynomials by a secret offset. These components are deployed in a range of lattice-based and code-based Key Encapsulation Mechanisms (KEMs) …
