Abstract
A technique includes providing a security monitor to at least detect a penetration attack on a circuit assembly that contains the security monitor. The technique includes inhibiting success of the penetration attack, including flexibly mounting the security monitor to the circuit assembly to allow the security monitor to move in response to the security monitor being contacted during the penetration attack.
Claims20
An apparatus comprising:
- an enclosure;
- a penetration detection layer that provides an electrical response to a physical penetration attack on a secure region inside the enclosure;
- and
- an assembly disposed in the secure region, the assembly comprising:
- a circuit board comprising an electrical circuit, the electrical circuit being coupled to the penetration detection layer to detect the electrical response;
- and
- a spring mount attached to the circuit board to allow physical movement of the circuit board when contacted during the physical penetration attack, the movement of the circuit board creating or extending a time period between a time that the physical penetration attack contacts the circuit board and a time that the physical penetration attack disables at least part of the electrical circuit, wherein the electrical circuit performs one or more operations in response to the physical penetration attack during the time period.
4 more elements
An apparatus comprising:
- a first substrate;
- an integrated circuit mounted to the first substrate;
- a base substrate;
- and
- a flexible mounting to suspend the first substrate over the base substrate and to allow the first substrate to move physically toward or away from the base substrate in response to the first substrate being subjected to a physical force directed toward or away from the base substrate during a physical penetration attack, wherein the movement of the first substrate creates or extends a time period between a time that the physical penetration attack contacts the first substrate and a time that the physical penetration attack disables at least part of the integrated circuit,
- wherein the integrated circuit is configured to detect the physical penetration attack and take corrective action in response to the penetration attack.
3 more elements
An apparatus comprising:
- a first substrate;
- an integrated circuit mounted to the first substrate;
- a second substrate arranged in parallel with the first substrate;
- and
- one or more penetration detection traces mounted to the second substrate;
- wherein the first substrate and the second substrate are flexibly coupled to allow the first substrate to move physically toward or away from the second substrate in response to the first substrate being subjected to a physical force directed toward or away from the second substrate, wherein the movement of the first substrate creates or extends a time period between a time that the physical force contacts the first substrate and a time that the physical force disables at least part of the integrated circuit,
- wherein the integrated circuit receives an electrical response from the one or more penetration detection traces in response to at least one of the one or more penetration detection traces being physically contacted by a tool.
