Abstract:Bit-slicing is a software implementation technique that treats an N-bit processor datapath as N parallel single-bit datapaths. The natural spatial redundancy of bit-sliced software can be used to build countermeasures against implementation attacks. While the merits of bit-slicing for side-channel countermeasures have been studied before, their application for protection of post-quantum algorithms against fault injection is still unexplored. We present an end-to-end analysis of the efficacy of bit-slicing to d… Show more
