Spoof proofing RA / Bluetooth Low Energy

[tofalck]

Would it be feasible to spoof proof BLE's by e.g. putting a code or even a public encryption key into one of the slots of the BLE beacons and have RA authenticate using the code or strong encryption?

This way a spoofer can't listen for beacons and put just the ID's into an app to get RA to transmit data from a fake beacon.
