摘要
Integrated circuit comprising the following characteristics:a circuit used for storing or processing data (110); anda radiation-resistant thyristor structure (120), which is configured to connect two power supply connections (130, 140) of the integrated circuit with short circuits,where the thyristor structure (120) is configured to provide an attractive means of illuminating a region of the thyristor structure (120) with radiation for which the thyristor structure (120) is sensitive to an electrically conductive connection between a first power supply connection (130)to produce the power supply connections of the integrated circuit and a second power supply connection (140) of the power supply connections of the integrated circuit;andwhere the thyristor structure (120) is so configured that a power density of the radiation required to switch on the thyristor structure (120) is lower than a power density of the radiation required to change data from the circuit used to store or process data (110);where the circuit used for storing or processing data (110) includes a storage unit (110) for storing a logical state;where the integrated circuit also includes a cryptographic processor (610, 710);where the storage unit (110) is configured to store information from the cryptographic processor (610, 710);andwhere the integrated circuit is configured to influence a function of the cryptographic processor (610, 710) appealing to the activation of the thyristor structure (120).
