Interactive · Glow CHERI meter with edge AI
The grid’s new front door
By the front door of an ordinary home is a device that measures the electricity and decides what the battery, charger and heat pump do. Pick an attack and a defence, then run one day at that address. The day stops at each event, so you can see exactly where it goes wrong, or where it is held.
Ready
Choose an attack and the device by the door, then run the day.
What happened
- A normal January morning.Heat pump warming the house; battery charged overnight at 4p; car at 80%.
Now multiply it
Fleets share firmware, so a bad day is never one house. Drag the slider to see when a household problem becomes a national one.
Illustrative: frequency falls linearly with the swing, anchored on the published reference of about 4.5 GW to reach 49 Hz. The real grid has reserves, inertia and protection schemes; the point is the scale, not the decimal.
Each layer stops a different attack
Memory safety stops the exploit. Local intelligence stops the instruction. A well-formed malicious command contains no memory bug, which is why the device by the door needs both.
| Attack | Conventional controller | Glow CHERI meter | CHERI + edge AI |
|---|---|---|---|
| Firmware takeover | Cold house, £5 lost, car at 22% | Normal day: exploit trapped | Normal day, attempt logged |
| Rogue dispatch | Battery dumped, car late | Same: no memory bug involved | Refused; home keeps its plan |
| Privacy harvest | Attacker knows when you’re out | Read blocked | Blocked; less data leaves anyway |
