Abstract
Disclosed in the present application are a high-temporal-accuracy power glitch fault injection method and apparatus for a cryptographic chip. According to the method, power glitch fault injection time is adjusted by considering rise time of a power glitch fault, so that the power glitch fault injection time is controlled more accurately, the limitation of the power glitch fault injection in temporal accuracy is reduced, and the success rate of the power glitch fault injection is increased.
