Its installation components and methods with an integrated circuit having a crypto processor

摘要

To prevent the risk that for a component of the integrated circuit type, equipped with crypto processor having SOLVED] private key, the error injection from the outside, from being stolen the secret key by the motion analysis. In order to protect against attacks aimed at revelation of a secret, the components of the integrated circuit type, equipped with [SOLUTION] crypto processor, and high for the triggering of the parasitic bipolar transistor and / or trigger the parasitic thyristor and (latch-up) to envisage circuit with the characteristics or by using the components sensitivity is assumed. components become unusable temporarily immediately by even if the component is attacked, this circuit is present, the revelation of a secret is hampered in practice.
