TSM and HO-TSM Supplementary Repository

This repository provides the supplementary material corresponding to two research papers:

  • TSM/ — Time Sharing Masking (TSM), published in TCHES 2024
  • HO_TSM/ — Higher-Order Time Sharing Masking (HO-TSM), published in TCHES 2025

Both contributions introduce efficient, low-latency masking schemes for securing hardware implementations of cryptographic algorithms against side-channel attacks.

Repository Contents

Each folder includes:

  • A local README.md with build and verification instructions
  • Verilog source files (rtl/)
  • Synthesis scripts, verification setups and logs, netlists, and related material
  • Simulation testbenches (sim/)
