Browsers would need to be modified, but I wonder if TOR's method of URLs with the public key encoded could be repurposed for devices on a LAN? https://hashhash.lan/ https://hashhash.lan/ (Causes browser to broadcast a message on LAN and wait for a response. Keys are exchanged and if valid, completes connection.) Devices would need to be programmed with a private key at the factory and print out a QR with the encoded hash and stick it somewhere discreet. What's that? The factory is producing devices all with the same private key to save money? This is why we can't have nice things.
