| 摘要 |
The disclosure relates to a method for detecting an attack in an electronic microcircuit, comprising: forming the microcircuit in a substrate, forming in the substrate a first well electrically isolated from the substrate, by a second well and an embedded well, forming in the first and second wells a data processing circuit comprising a ground terminal formed in the first well and a power supply terminal formed in the second well, and activating a detection signal when a voltage at the ground or power supply terminal of the data processing circuit crosses a threshold voltage.
