Raccoon, presented at CRYPTO 2024, is a provably secure lattice-based signature scheme featuring an $O(d \log{d})$ masking overhead. Although it did not advance beyond the first-round of NIST's additional call for post-quantum digital signatures, Raccoon remains a promising candidate due to its low masking overhead and strong provable side-channel resistance. This paper proposes the first efficient and compact implementation of high-order Raccoon on the ARM Cortex-M4, with a focus on opt
