![]() Indeed, many side-channel analysis techniques have proven successful in breaking an algorithmically robust cryptographic operation and extracting the secret key. ![]() ![]() These attacks pose a serious threat to modules that integrate cryptographic systems. Examples include supply current, execution time, and electromagnetic emission. This can be achieved by measuring or analyzing various physical parameters. ![]() Countermeasures: Preventing Side-channel attacksĪ side-channel attack ( SCA) is a security exploit that attempts to extract secrets from a chip or a system.Technical example of a differential power analysis attack.What attacks use side channel analysis?.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. We also explore differential power analysis (DPA), an extremely powerful side-channel attack capable of obtaining and analyzing statistical measurements across multiple operations. We describe how side-channel attacks work and detail some of the most common attack methodologies. ![]() In this blog post, we take an in-depth look at the world of side-channel attacks.
