Abstract:It is well known in the embedded security field that the power consumed by a device depends on the operations and data that they process at that moment in time. This information can leak and help to extract secret information such as cryptography keys. Protecting devices from these attackers requires Side Channel Analysis (SCA) countermeasures that add randomness to the power traces, making exploiting leakages challenging. Alignment problems are also common in genetics, where they use alignment methods to study biological relationships between species and ancestors. This work presents a new method for the alignment of power traces that implements ideas from bioinformatics and shows more effective alignment by using fewer power traces to extract cryptography keys than existing methods.
