Abstract

A tamper respondent module includes a basecard adapted to be inserted into a slot in a rack enclosure comprising at least one guide edge, at least one electrical coupler, a surface and at least one electronic component that contains information in an electronic format. In one example, an outer cover is coupled to the basecard and includes at least five sides. The outer cover is arranged in a covering relationship over the at least one electronic component. In another example, an anti-tamper apparatus is disposed between the outer cover and the surface. In another example, an anti-tamper circuit is electrically coupled to the at least one electronic component. In another example, a thermal frame is thermally coupled to the at least one electronic component.

Claims

1. A tamper respondent module, comprising:

a basecard adapted to be inserted into a slot in a rack enclosure comprising at least one guide edge, at least one electrical coupler, a surface and at least one electronic component that contains information in an electronic format;

an outer cover coupled to the basecard, comprising at least five sides with at least one side being oriented generally parallel to the surface and spaced a distance from the surface, and a plurality of the remaining sides being disposed adjacent to the surface of the basecard, the outer cover being arranged in a covering relationship over the at least one electronic component and at least partially over the surface of the basecard; and

further comprising an anti-tamper apparatus disposed between the outer cover and the surface, and adapted to have electromagnetic energy distributed therein, damage to the anti-tamper apparatus resulting in a detectable variation of the electromagnetic energy distribution of the anti-tamper apparatus.

2. The tamper respondent module of claim 1, further comprising an anti-tamper cover arranged in a covering relationship at least partially over the surface of the basecard and being disposed between the outer cover and the basecard.

3. The tamper respondent module of claim 2, wherein the anti-tamper apparatus is at least partially disposed between the outer cover and the anti-tamper cover.

4. The tamper respondent module of claim 2, wherein the anti-tamper apparatus is coupled to at least one of the outer cover and the anti-tamper cover.

5. The tamper respondent module of claim 1, further comprising an anti-tamper circuit electrically coupled to the at least one electronic component and comprising a power source, the anti-tamper circuit being adapted to alter or destroy the information contained in the at least one electronic component in response to an indication that the anti-tamper apparatus is damaged.

6. The tamper respondent module of claim 5, further comprising an auxiliary anti-tamper apparatus coupled at least partially about the anti-tamper circuit, damage to the auxiliary anti-tamper apparatus resulting in a detectable variation to a characteristic of the auxiliary anti-tamper apparatus, and wherein the anti-tamper circuit is further adapted to alter or destroy the information contained in the at least one electronic component in response to an indication that the auxiliary anti-tamper apparatus is damaged.

7. The tamper respondent module of claim 1, wherein the outer cover is opaque such that the at least one electronic component is not visible when the outer cover is coupled to the basecard.

8. The tamper respondent module of claim 1, wherein at least one of the plurality of sides disposed adjacent to the surface of the basecard further comprises a flange adapted to couple said side to the surface.

9. The tamper respondent module of claim 1, further comprising at least one sensor forming an electrical circuit, wherein the sensor is configured to detect removal of the outer cover from the surface.

10. The tamper respondent module of claim 1, further comprising a thermal frame that is at least partially enclosed by the outer cover and thermally coupled to the at least one electronic component, the thermal frame being configured to transfer thermal energy away from the at least one electronic component and towards an environment located outside of the outer cover.

11. The tamper respondent module of claim 10, wherein the thermal frame extends a distance beyond the outer cover and is thermally coupled to external structure located within the environment outside of the outer cover.
