Abstract
Methods and apparatus are provided for sampling an indicator of the internal state of an embedded system or integrated circuit, where the indicator is sampled in a manner synchronous to the internal clock of the embedded system or integrated circuit. The resulting samples can be used for determining secret data within the embedded system or integrated circuit, detecting failures, or detecting counterfeit devices.
