* Split the sdcard into two partitions one smal wich contains the bootloader, kernel and initrd and an encrypted root filesystem.
|
|
* Integrate Tor into initrd
|
|
* calculate a hash with sensors wich messure the enviroment (pressure against a case, eg.)
|
|
|
|
If the Pi hast power and a network conetcion ...
|
|
|
|
- it can calculate the hash
|
|
- start the tor client
|
|
- ask a specific hidden service with the hash for a key
|
|
- if the hash is korect it return the key wich unlook the rootfs
|

> An external unlocatable party checks if the device was touched
