Abstract:
In order to protect an integrated circuit provided with a cryptoprocessor from attacks aiming to reveal secrets, it is anticipated to use a component sensitive to the activation of a parasitic (latchup) thyristor and/or to the activation of a parasitic bipolar transistor, or to design a circuit having this property. If the component is stressed due to the presence of this circuit, it is immediately deactivated, actually preventing the revelation of the secrets thereof.
