Why ?
They could embed some sort of a trusted platform module with crypto and (physical) intrusion detection, just like payment terminals.
If you open the case, the system deletes the keys and you can say bye-bye to your contract.
- LeifCarrotson 10y agoPhysical intrusion detection can be defeated. All it takes is one person to open it up to document where the microswitches are, and a careful bit of work with some tin snips and you're in.
- jotux 10y agoYes all physical security can be defeated but you could make it exceptionally difficult to do. As an example, I used to work on financial terminals and sat across the isle from one of the security engineers. They actually embedded conductors in the case that created a known EM field when the case was closed. If you opened the case, it disturbed the field and erases the keys. If you drill a hole in the case, it disturbs the field. If you melt the case and insert a metallic object (screw driver or knife) it disturbs the field. This was just one of the physical security measures. tl;dr - modern physical security is much more than microswitches.
