In a high security situation. It would not be a password, but a smartcard which authenticates the device before providing its key, and the device authenticating the smartcard. Edit: For the purposes of the Networked Evil Maid Attacks. Mutual Authentication (of device and user) is currently the purpose of research. It has not needed to be implemented yet as the regular Evil Maid is still possible due to the fact that Secure Boot is currently the easier target to circumvent. Once Secure Boot becomes harder to circumvent and old "assumed" buggy kernels are revoked from running. Networked Evil Maid counter measures will need to be implemented as standard
