About encryption for iot device/snap

i find there is no encryption function on ubuntu core. it means my x86 device which use msata SSD have no protection. If someone get our device, it’s easy to get the raw code from SSD. i have read about hardware encryption, but it is not easy for us to do it on hardware.
And another way of encrtption, Can i encrypt snap when squashfsing it? If we make our snap suitable for ubuntu core on x86/arm, it will be risky for us to authorize others to use our software.If snap can be encrypted,at least it’ll take a very long time to type in the current code to unsquashfs it…
Is there a plan about adding encryption or similiar to make our devices more safe?
