> When a device goes missing and can’t connect to Wi-Fi or cellular—for example, a MacBook left on a park bench—it begins periodically broadcasting the derived public key Pi for a limited period of time in a Bluetooth payload. By using P-224, the public key representation can fit into a single Bluetooth payload. This is clever, and the reason Apple chose P-224 specifically. |
