Abstract
The disclosure relates to voltage glitch detection in an integrated circuit for detection of fault injection attacks. Example embodiments include an integrated circuit comprising: a hardware accelerator including a computing module configured to perform a computing function; and a glitch detector including a delay function and a comparator arranged to compare an output from the delay function with an expected result to provide an output for detecting a glitch, wherein the delay function of the glitch detector is provided at least in part by the computing function of the computing module in the hardware accelerator.
