Does what I'm calling a "barge-in attack" exist for Bluetooth Low Energy? This is a type of Man-in-the-Middle attack, I guess, but unlike in most discourse on BLE security, the attacker does not create two connections, one with the Central and one with the Peripheral, and forward packets between the two. The attacker "barges in" on an active, unencrypted connection by jamming certain packets such that one device drops the connection while the other continues communicating with the attacker, believing that it is the original peer.
For BLE, I think this can be done by jamming Device A's transmissions until Device B's supervision timeout elapses. Wouldn't Device A's Link Layer keep re-transmitting, as Device B's packets will be left intact, just with a non-incrementing Next Expected Sequence Number? Eventually, Device B will stop sending packets, and the attacker may substitute their own for the remainder of the connection.
Also, does this attack have a more common name?
