Abstract
In the preceding discussion, we have presented to the readers a variety of fault attacks on a wide range of cryptographic algorithms across hardware and software-based implementations. It is therefore established, by now, that fault attacks are a serious threat to the security of hardware implementations, and consequently, sound countermeasures must be designed to tackle such threats. In this section, we present a classical approach popularly employed to resist such attacks, namely detection. Since most of the fault attacks described so far exploit transient faults during algorithm execution rather than permanent faults in the target device, the countermeasure strategy is to detect any such occurrence of faults during every execution of the cryptographic algorithm.
