Abstract
An integrated circuit for hardware security comprises a voltage glitch detection processing system comprising an oscillator circuit that generates and outputs a local oscillator clock which is a function of a supply voltage; a counter clocked by the oscillator circuit to generate at least one count value; and a capture section that synchronizes the at least one count value into a system clock domain for detecting a voltage glitch in the supply voltage.
