Side-channel attacks (SCA) comprise a wide range of techniques including Differential Power Analysis (DPA), Simple Power Analysis (SPA), Simple Electromagnetic Analysis (SEMA), Differential Electromagnetic Analysis (DEMA), Correlation Power Analysis (CPA) and Correlation Electromagnetic Analysis (CEMA). An effective layer of side-channel countermeasures should therefore be implemented via hardware (DPA resistant cores), software (DPA resistant libraries) or both. After layered countermeasures have been implemented, systems should be carefully evaluated with a Test Vector Leakage Assessment (TVLA) platform such as the Rambus DPA Workstation (DPAWS) to confirm the cessation of sensitive side-channel leakage.
