ESPM-D: Efficient Sparse Polynomial Multiplication for Dilithium on ARM Cortex-M4 and Apple M2

arXiv:2404.12675v1 Announce Type: new
Abstract: Dilithium is a lattice-based digital signature scheme standardized by the NIST post-quantum cryptography (PQC) project. In this study, we focus on developing efficient sparse polynomial multiplication implementations of Dilithium for ARM Cortex-M4 and Apple M2, which are both based on the ARM architecture. The ARM Cortex-M4 is commonly utilized in resource-constrained devices such as sensors. Conversely, the Apple M2 is typically found on mobile devices, emphasizing high performance and versatility. Accordingly, our optimization strategies differ …
