A Non Profiled and Profiled Side Channel Attack Countermeasure through Computation Interleaving
Isabella Piacentini, Alessandro Barenghi, Gerardo Pelosi · 2023
Side channel attacks analyse devices to retrieve secret informations. These attacks can be performed using either a synthetic model or by profiling a specific instance of the targeted design. Our proposal is a novel countermeasure characterized by temporal interleaving of the computation. This approach improves upon existing methods by rendering the profiled models of a device non-portable and offering resistance against first-order non-profiled attacks. The assessment of the security of our proposed approach covers scenarios of profiled attacks with feature reduction techniques, both under a single-device and multi-device model, as well as first-order non-profiled attacks. Our design demonstrates improved results in terms of resource consumption and timing when compared to alternative solutions.
