A tamper respondent enclosure (10) comprises a wall including at least two layers (34, 35; 34, 24). A first layer of the wall (34) comprises a sheet of insulating material (36) having lines of conductive material (38, 39) on first and second sides thereof, the lines forming part of a sensor circuit. A detector (16) is provided part of a sensor circuit. A detector (16) is provided for detecting an interruption in the circuit. A second layer of the wall (35; 24) comprises an area of conductive material (40, 41; 24) separated from the lines (38, 39) by insulating material. The detector (16) will also detect an electrical connection between the lines and the conductive area. The layers of the wall are arranged such that, at any point in the wall, the wall section includes at least one of the lines and the conductive area. |
