Hidden OS encryption for Linux ?

Hi before I start trying out linux just wanted to find out if Linux encryption has support for hidden os to give plausible deniability ?

 

I haven't heard of that. Buy it's been maybe a year since I looked.

The closest that I know is this dance:

• install with /boot on flash card and dm-crypt/LUKS FDE
• back up LUKS header to /boot card
  
• delete LUKS header
• after shutdown, keep /boot card safe; make a backup copy
• bootup into initramfs busybox
• restore LUKS header
• reboot normally

While the LUKS header is gone, the disk is totally random. And without the /boot card, there's no information about a dm-crypt/LUKS volume existing.

Maybe there's a way to integrate that into a Windows/Linux dual boot. The dm-crypt/LUKS volume could be on an apparently empty disk. But if Windows started messing with it, you might be hosed. You could probably put it on a SSD in a toaster-style SATA drive holder. The machine would boot into Windows unless the /boot card and SSD were present.

 

thanks great idea, yeah I googled it but not much information was showing up it did not look like it was possible but the post were 2-3 years ago.
