Abstract
Apparatus that can detect chassis tamper events are disclosed. One apparatus includes a chassis including a secure area housing a secure element within the chassis and a security switch coupled between the chassis and the secure area. The security switch includes a switch and a processor in which the switch is configured to mechanically trigger to a tamper state from a non-tamper state in response to a chassis tamper event occurring between the chassis and the secure area and to be electrically reset to the non-tamper state from the tamper state in response to receiving a reset signal from the processor. Methods and computer program products that can perform chassis tamper event and switch reset functions for the apparatus are also disclosed.
