The static power consumption in modern integrated circuits has become a critical standpoint in side-channel analysis. As it has been widely demonstrated in the technical literature, it is possible to extract secret information from a cryptographic circuit by means of static current measurements. Static and dynamic power analysis require different measurement procedures, due to physical reasons. In...
Security of sensible data for ultraconstrained IoT smart devices is one of the most challenging task in modern design. The needs of CPA-resistant cryptographic devices has to deal with the demanding requirements of small area and small impact on the overall power consumption. In this work, a novel current-mode feedback suppressor as on-chip analog-level CPA countermeasure is proposed. It aims to suppress...
In this work, the implementation of the PRESENT-80 block cipher in a 40nm CMOS technology, and its vulnerability to Side Channel Attacks Exploiting Static Power is investigated. In the last two decades, several countermeasures to thwart DPA/CPA attacks based on the exploitation of dynamic power consumption have been proposed. In particular, WDDL logic style is a gate-level countermeasure, to Power...
