A Cryptographic Coarse Grain Reconfigurable Architecture Robust Against DPA
Abstract
This work addresses the problem of information leakage of cryptographic devices, by using the reconfiguration technique allied to an RNS based arithmetic. The information leaked by circuits, like power consumption, electromagnetic emissions and time to compute may be used to find cryptographic secrets. The results issue of prototyping shows that our coarse grained reconfigurable architecture is robust against power analysis attacks.
