4 Hardware Trojans in Microcircuits
Fig. 4.55
Bitwise key extraction using an upgraded block of 56 scanning triggers, where it is stored (a), and transmitting a bit of a stolen key by manipulating
the amplitude or frequency of the UWB transmission (b). (Hardware modifications for Trojans are shown in gray; ms: signal mode)
