From Apple Platform Security Guide [0] : > The individual messages are encrypted much like messages in iMessage are. After the devices are paired, each device generates a symmetric 256-bit AES key that gets stored in the device’s keychain. This key can encrypt and authenticate the BLE advertisements that communicate the device’s current activity to other iCloud-paired devices using AES256 in GCM mode, with replay protection measures.
