We didn’t use to think too much about physical computer security because most computers were safely stored in our homes or businesses. But many people today use laptops which can be lost or stolen while traveling or toting them back and forth to work. Having physical access to a computer makes it much easier for bad guys to hack into them and steal our data. By “sniffing” the data signals on the wires in computer motherboards, bad guys can actually pull out security keys that would allow them to bypass encrypted hard drives and account authentication. To combat this, Microsoft’s Pluton project makes this data exfiltration much, much harder by embedding the security circuitry directly into the CPU chip where the “wires” are microscopic and embedded in plastic casings.
