Hello
As you know, voltage glitch attack (VGA) is a fault injection technique that exploits deliberately abrupt variation of the voltage level at the power supply of a CC. Voltage glitches can lead to misinterpreting instructions of (crypto-) processor, failure to erase or overwrite data or retaining data from memory when not instructed.
In general I want to protect my MSP430 powered at 3.3V from this type of attack. I was searching some kind of bidirectional TVS, eFuse or also some multiphase voltage regulator (MPVR) or a combination of them...
But to be honest I am not sure is this is going to work or not in order to avoid VGA. Do you recomend me some circuit or IC to implement that?
Thanks in advance.
Jose.
