Higher-Order Masked Saberide-channel attacks is masking. In this work, we present a detailed study of higher-order masking techniques for the key-encapsulation mechanism Saber. Saber is one of the lattice-based finalist candidates in the National Institute of Standards of Technology’s post-quantum standardization procedure.

Mix-Nets from Re-randomizable and Replayable CCA-Secure Public-Key Encryptionbased on Public-Verifiable Re-randomizable Replayable CCA-secure (Rand-RCCA) PKE schemes. The bottleneck of their approach is that public-verifiable Rand-RCCA PKEs are less efficient than typical CPA-secure re-randomizable PKEs. In this paper, we revisit their mix-net protocol, showing how to get ri
