ABSTRACT:
A device (10) for protecting stored sensitive data includes a housing (12) formed by six plates P1-P6 inclusive each carrying a conductive path segment formed by thick film deposition techniques and each having a winding configuration covering substantially the entire inner surface of the plate. The four side plates P2-P5 inclusive are mounted on a printed circuit board (PCB 14) which is mounted on the base plate (P6). The conductive path segments on the side and base plates (P2-P6 inclusive) are interconnected to form a wire mesh by conductive epoxy material connecting the path segments on the side and base plates (P2-P6 inclusive) with conductive tracks on the PCB (14). The conductive path segment on the top plate (P1) is connected by conductive wires (58, 60), which extend through plated through holes (B9, B10) in the PCB (14).
