Claim of US Patent No. 10,251,260

1. A secure electronic system comprising:a security housing comprising:
a non-conductive housing, and
a housing portion of a tamper detection circuit;
a plurality of connector pieces connecting the housing portion of the tamper detection circuit to a board portion of the tamper detection circuit, thereby completing the tamper detection circuit; and
a circuit board, wherein at least a portion of the circuit board is covered by the security housing, the circuit board comprising:
a board,
the board portion of the tamper detection circuit including a voltage monitor node, wherein the board portion of the tamper detection circuit detects tampering with the tamper detection circuit by detecting a voltage change along the tamper detection circuit using the voltage monitor node, and
a plurality of board connector piece holders, wherein each board connector piece holder of the plurality of board connector piece holders includes conductive material and holds a connector piece of the plurality of connector pieces without forming an electrical connection between the conductive material and the connector piece unless tampered with, wherein electrical contact between the conductive material of at least one of the plurality of board connector piece holders and the tamper detection circuit indicates tampering and causes the voltage change along the tamper detection circuit that is detected using the voltage monitor node.
