Benchmarking of nanometer technologies for DPA-resilient DPL-based cryptocircuits

The design of cryptographic circuits is requiring greater performance restrictions due to the constrained environments for IoT applications in which they are included. Focusing on the countermeasures based on dual-precharge logic styles, power, area and delay penalties are some of their major drawbacks when compared to their static CMOS single-ended counterparts. In this paper, we propose a initial study where scaled CMOS technnology and FinFET emerging technology are considered to foresee the relationship between ultra low power consumption, reduced delay, and security. As demonstration vehicle, we measure the performance and the security level achieved by different Substitution Boxes, implemented in different technologies. As main results, nanometer CMOS technologies maintains considerable security levels at reasonable power and delay figures, while FinFETs outperform CMOS in power and delay reduction, but with a non negligible degradation in security.
