A security system for an electrical circuit comprises a first circuit board, a second circuit board, a protective casing interposed between the first and the second circuit boards, a flexible conductive film wrapped around the protective casing, a first electrical connector in contact with the first and second circuit boards, and a tamper detection circuit connected to the first electrical connector. The tamper detection circuit detects whether the first electrical connector is in contact with both the first and second circuit boards and whether the integrity of the flexible conductive film has been compromised.
Un système de sécurité pour un circuit électrique comprend une première carte de circuit, une deuxième carte de circuit, un boîtier protecteur entre les deux cartes de circuit, une pellicule conductrice souple enveloppant le boîtier protecteur, un premier raccord électrique en contact avec les deux cartes de circuit, et un circuit de détection de fraude raccordée au premier raccord électrique. Le circuit de détection de fraude détecte si le premier raccord électrique est en contact avec les deux cartes de circuit et si l'intégrité de la pellicule conductrice souple a été compromise.
