I know about the OS. But the key is fused, not in flash in the CPU. So they probably have cmos style persistence and not true one. Which is vulnerable to erasing. Low voltage attacks: A low-voltage fault attack is a fault attack where the fault is induced by feeding the hardware with a lower-than-normal voltage (in the "smart card" model, the card has its own CPU, RAM and ROM, but the current and clock signals are provided externally, i.e. are under the control of the attacker). For instance, if the card expect 3.3V, you give it only 2V. The real trick here is that the attacker can lower the voltage for only very short durations, a few clock cycles, so as to induce a fault in a specific part of the algorithm execution We try to get the hardware crazy. http://security.stackexchange.com/questions/69279/what-actually-happens-in-low-voltage-fault-attacks http://security.stackexchange.com/questions/69279/what-actua...
