How to create a hidden OS with access by a key file located on the network?

Question

Encryption

Please tell me if it is possible to create a hidden operating system on a disk, for example, through veracrypt, to access which a key file was used, or a token located on the network.

Answer 1

The distribution of password things over the network is unreliable, because it will be possible to detect such things from any machine on the same network.
And so. You organize a machine (for example, a virtual machine on a smartphone) distributing dhcp and tftpd for pxe network boot, in fact, only a boot disk over the network (I'm afraid for windows you will have to sweat, but in theory this is possible).
For linux, a similar scheme allows you to enter the password remotely by connecting via ssh to the mini server at the time of boot, for example, from the same smartphone. Those. all the fuss in setting up such a scheme is tools that would allow you to control from your smartphone what exactly was connected to the right hardware and there is no layer of an attacker / substitution of this hardware.
