Zusammenfassung:Manufacturing a batch is provided which includes a plurality of items of an electronic device, the items including a plurality of corresponding main modules having a same functional structure substantially identical for the items. The method includes defining at least one security electric circuit, of an enclosure component for enclosing each item, adapted to protect the item from tampering, the security electric circuits having individual configurations substantially different among the items, for use in forming the security electric circuit with the corresponding configuration on each enclosure component. Additionally, the method includes determining one or more electric characteristics of each security electric circuit for use in configuring a monitoring circuit of the corresponding main module, the monitoring circuit being adapted to the corresponding security electric circuit for detecting the tampering, according to the electric characteristics of the corresponding security circuits.
