    Abstract: There is provided a security module for protecting circuit components from unauthorized access. The security module comprises a base printed circuit board, base PCB, for supporting circuit components to be protected, a frame printed circuit board, frame PCB, where the frame PCB is secured on top of the base PCB and defining a protective space for circuit components supported by the base PCB, and a lid printed circuit board, lid PCB, which is secured on top of the frame PCB, thereby providing a top closure to the protective space. First and third meshes are provided in the frame PCB, and a second mesh is provided in the lid PCB. The first, second and third meshes have a number of electrically conductive tracks, and one or more tamper detection paths are formed comprising a serial connection of one track from each of the first, second and third meshes. The security module may further comprise security circuitry arranged on the base PCB within the protective space, and for each tamper detection path the security circuitry has a pair of electrical signal input/outputs being electrically connected to the tamper detection path.

    Abstract: There is provided a tamper responsive sensor comprising a carrier printed circuit board, carrier PCB, holding a mesh of one or more electrically conductive tracks. The sensor also holds a pressure or force sensitive switch contact arranged on top of the carrier PCB, which contact has first and second electrical contact connections. Furthermore, the sensor has a tamper detecting circuitry arranged at the carrier PCB, which circuitry is powered via two electrical power lines, and which circuitry is connected to one or more electrically conductive signal lines. One of the power lines or one of the signal lines is electrically connected to the tamper detecting circuitry via a first tamper line holding the switch contact, and one of the power lines or one of the signal lines is electrically connected to the tamper detecting circuitry via a second tamper line holding a conductive track of the carrier PCB mesh, thereby enabling the tamper detecting circuit to detect an interruption of the signal path through the first tamper line and/or an interruption of the of signal path through the second tamper line.
