Side-Channel Attacks
Abstract
Side-channel attacks (SCAs) aim at extracting secrets from a chip or a system, through measurement and analysis of physical parameters. Examples of such parameters include supply current, execution time, and electromagnetic emission. These attacks pose a serious threat to modules that integrate cryptographic systems, as many side-channel analysis techniques have proven successful in breaking an algorithmically robust cryptographic operation (for example, encryption) and extracting the secret key. In this chapter, we focus on different side-channel attack modalities in hardware implementations of cryptographic algorithms. Chapter 16, on the other hand, covers side-channels in a processor micro-architecture, ...
