Abstract
Side-channel attacks are a class of attacks where an attacker deduces the internal state of a device by observing information that leaks during the normal functioning of the device. In this chapter we describe side-channel analysis and its relevance to fault attacks. Side-channel analysis is typically used to extract information about cryptographic keys. However, we will be concentrating on how it can be used as a means to identify target operations and as a trigger mechanism for fault attacks.
