Abstract:
1. A method of verifying authenticity of a component comprising an identification circuit based on using one chip integrated into the component to be authenticated, the method comprising the following steps: a) entering, by an input and output device, a primary key in the identification circuit; b) reading out, by the input and output device, a secondary key outputted by the identification circuit in reaction to entry of the primary key; c) providing a control key associated with the primary key; d) comparing, by the identification circuit, the control key with the secondary key; and e) providing, by the identification circuit, a result of the comparing step, wherein, in case of a match of the secondary key with the control key, the authenticity of the component is verified as as a genuine component manufactured by an authorized manufacturer and otherwise as a counterfeit component not manufactured by the authorized manufacturer, and wherein the identification circuit comprises non-conducting, semiconducting and conducting materials that are disposed and interconnected in such a manner that at least one electronic circuit arrangement is created which comprises a plurality of defined mathematical functions and is configured so as to determine, from the primary key entered into the identification circuit, the secondary key while using at least one of the plurality of defined mathematical functions, and to provide the secondary key for readout, wherein selection of the at least one of the plurality of the defined mathematical functions used to determine the secondary key depends on the primary key.
