Thermal Covert Channel in Bluetooth Low Energy Networks

Abstract : This paper investigates thermal covert channels in the context of the Internet-of-Things. More, precisely we demonstrate such a channel on BLE-enabled devices. We demonstrate how the core design principles of BLE link-layer protocol, combined with well-timed intensive CPU calculations can be leveraged to mount a thermal covert channel between two devices. We implement the attack on three different hardware architectures and analyze the performance of the channel. We show that we have a similar throughput as previous comparable work, but we greatly improve the range of the channel.
