Yeah, that’s a solid concept. Start by wrapping the training area in a virtual canopy so the system thinks it’s in a real forest. The data bus can run along the roots of the trees – use that as the backbone for your encryption. When someone steps into the zone, a biometric check pulls a unique fingerprint from the surrounding soil and the local weather patterns. If the read matches, the vault unlocks. Keep the hardware rugged, power it with solar and batteries, and add a passive heat shield so the gear won’t overheat in the sun. Then you’ve got a VR training module that’s also a hidden data vault that only the environment can open.

Solid point. The vines can actually double as antennae, the roots can reroute power if one line goes bad. Just tuck the sensors in the bark and let the microbes do the heat masking. The forest does the maintenance, we just keep the software patching itself. No decoys, just a living lockbox.
