Side-channel attacks explained: everything you need to know
October 14, 2021
We describe how side-channel attacks work and detail some of the most common attack methodologies. We also explore differential power analysis (DPA), an extremely powerful side-channel attack capable of obtaining and analyzing statistical measurements across multiple operations. In addition, we provide a walkthrough of a DPA attack and explain how different countermeasures with varying levels of effectiveness can be used to prevent side-channel attacks.
