Power Analysis Attacks and Countermeasures

This article focuses on power analysis attacks because they have received by far the most attention in recent years. They are powerful and can be executed relatively easily. This article provides an introduction to these attacks and discusses countermeasures against them. In particular, we focus on countermeasures that can be implemented at the cell level. This article presents an overview of power analysis attacks, which are based on the measurement of the power consumed by cryptographic ICs, and countermeasures against them.
