| 摘要 |
The invention relates to a device having a carrier having circuit structures, which have a complex impedance, comprising a measuring apparatus, which is designed to measure the complex impedance of the circuit structures at a first time in order to obtain a first result and at a later, second time in order to obtain a second result. Furthermore, either a controller, which is designed to enable operation of a component or to evaluate whether unauthorized access to the component has occurred, in dependence on whether the first result corresponds with the second result, or an interface, which is designed to transmit the first result and the second result to such a controller in a wired or wireless manner, is provided. Specially embedded systems without integrated security functions can thus be equipped with cryptographic routines simply and economically. |
