Would there be a way for the bluetooth device to rotate its broadcast keys in a predictable way to avoid the iphone notification of "unknown airtag close by" messages? Seems like this could be exploited for surveillance.
- mrshadowgoose 2y agoSure, that works. One can also just cycle through a sufficiently large bank of pre-allocated keys, such that a findmy receiver doesn't see the same key too frequently.
- denysvitali 2y agoYou just need to derive a new key, this process is already part of the protocol to avoid being tracked while you wear your airtag
- denysvitali 2y agoTechnically it would need to rotate every 15 minutes or so - the notification you're talking about happens when the device is in "lost mode" (away from its owner): in that case the key is rotate every 24 hours
