A thermoconductive curable liquid polymer composition including a curable liquid polymer, a filler made from a thermally-elongatable shape-memory alloy, and a thermoconductive filler other than. The first RC network and the second RC network each have a time constant substantially equal to the ratio between the inductance and the DC resistance of the inductor. The test signal may be applied along the power conductors or along isolated conductors dedicated to the tamper detection system. The circuit is adapted to use the table to associate the packet with one of the packet flows and based on the association, interact with the second interface to selectively transfer a portion of the packet to the system memory for processing by the processor.
