Zero-Value Filtering for Accelerating Non-Profiled Side-Channel Attack on Incomplete NTT based Implementations of Lattice-based Cryptography

ePrint Report: Zero-Value Filtering for Accelerating Non-Profiled Side-Channel Attack on Incomplete NTT based Implementations of Lattice-based Cryptography

Tolun Tosun, Erkay Savas

Lattice-based cryptographic schemes such as Crystals-Kyber and Dilithium are post-quantum algorithms selected to be standardized by NIST as they are considered to be secure against quantum computing attacks. The multiplication in polynomial rings is the most time-consuming operation in many lattice-based cryptographic schemes, which is also subject to side-channel attacks. While NTT-based polynomial multiplication is almost a norm in …
