Area Efficiency in Constant-Cycle Schemes

Boolean masking is a widely used countermeasure to protect hardware implementations against side-channel attacks. However, combining security with low latency remains challenging, since in many composed masked designs the latency increases with the number of cascaded non-linear operations. Constant-cycle masking scheme...

Coupling Leakage in Theory and Practice

With the widespread adoption of Field Programmable Gate Arrays (FPGAs) in security-critical industries such as defense and telecommunications, ensuring the confidentiality of sensitive data processed by these devices has become paramount. Side-Channel Analysis (SCA) poses a significant threat, necessitating the protect...

Coupling Leakage in Theory and Practice - Unveiling (Post-PnR) Security Flaws in Masked FPGA-Mapped Designs

Hardware Private Cubic Circuits

HPCC is presented, the first low-latency 3-input multiplication gadget for arbitrary fields that maintains a constant latency of one cycle, independent of the number of shares, and is leveraged to implement the first composable AES S-Box with two cycles of latency with an arbitrary number of shares.
