Gadget-based Masking of Streamlined NTRU Prime Decapsulation in Hardware
Abstract: Streamlined NTRU Prime is a lattice-based Key Encapsulation Mechanism (KEM) that is, together with X25519, the default algorithm in OpenSSH 9. Based on lattice assumptions, it is assumed to be secure also against attackers with access to< large-scale quantum computers. While Post-Quantum Cryptography (PQC) schemes have been subject to extensive research in recent years, challenges remain with respect to protection mechanisms against attackers that have additional side-channel information, such as the power consumption of a device processing secret data. As a countermeasure to such attacks, masking has been shown to be a promising and effective approach. For public-key schemes, including any recent PQC schemes, usually, a mixture of Boolean and arithmetic techniques is applied on an algorithmic level. Our generic hardware implementation of Streamlined NTRU Prime decapsulation, however, follows an idea that until now was assumed to be solely applicable efficiently to symmetric crypto.... https://tches.iacr.org/index.php/TCHES/article/view/11238
