Claim Text:
1. A system of securely paired Bluetooth devices comprising: a host device comprising an audio interface and a Bluetooth transceiver; a peripheral device comprising an audio interface and a Bluetooth transceiver; wherein the Bluetooth transceiver of the host device and the Bluetooth transceiver of the peripheral device are in an idle power state when the host device and the peripheral device are not securely paired; wherein the host device and the peripheral device are configured to connect to each other by physically connecting their corresponding audio interfaces and to communicate with each other by establishing an out-of-band audio communication channel through the connected audio interfaces; wherein the host device and the peripheral device are configured to exchange Bluetooth authentication data via the out-of-band audio communication channel; and wherein the host device and the peripheral device are configured to be securely paired with each other by establishing an authenticated and cryptographically protected in-band Bluetooth communication channel with each other and wherein the in-band Bluetooth communication channel is established by the Bluetooth transceiver in the host device and the Bluetooth transceiver in the peripheral device transitioning from the idle power state to an operating state, and initializing the corresponding Bluetooth transceivers with the corresponding exchanged Bluetooth authentication data.
