Raccoon: A Masking-Friendly Signature Proven in the Probing Model
Abstract
This paper presents Raccoon, a lattice-based signature scheme submitted to the NIST 2022 call for additional post-quantum signatures. Raccoon has the specificity of always being masked. Concretely, all sensitive intermediate values are shared into 𝑑 parts. The main design rationale of Raccoon is to be easy to mask at high orders, and this dictated most of its design choices, such as the introduction of new algorithmic techniques for sampling small errors. As a result, Raccoon achieves a masking overhead
Note: Added proofs and corrected statements (see Footnotes 4 and 5).
