Abstract
Power analysis is a powerful technique which extracts secret information from smart cards during the execution of their internal computations. For this reason, protecting smart cards against power attacks is of particular concern. In this paper, we propose a new hardware countermeasure, which decorrelates the power consumed by any digital circuit from the data internally elaborated. The new strategy is based on a new chargepump subsystem1 and can be used with any logic design style.File in questo prodotto:
