Differential Fault Analysis (DFA) is one of the most powerful techniques to attack cryptosystems. Several countermeasures have been proposed, which are based either on information or temporal redundancy. In this work, we propose a novel approach based on a Double-Data-Rate (DDR) computation template. A few sample architectures have been implemented: they are compared to other existing architectures and countermeasures, and a thorough dependability analysis is given.
