| Abstract(in English) | With the growing demand for Bluetooth devices, the power-saving mode of Bluetooth, which reduces the power consumption of devices, is supported by various devices. A characteristic of the power-saving mode is that the connection between devices becomes temporarily disconnected or near-disconnected. The authors proposed a DoS attack that h?acks established Bluetooth communications between devices, using the power-saving mode as a starting point. However, in the proposed DoS attack that starts from the energy-saving mode, it is impossible for the attacker to inject arbitrary commands, and the threats posed by the attack are limited. This paper proposes a link key h?ack attack on Bluetooth BR/EDR using the power-saving mode. In addition to the DoS attack initiated by the power-saving mode proposed by the authors, the proposed method involves sending a re-pairing request during the DoS attack to h?ack the link key, thereby enabling the injection of arbitrary commands. We also conduct experimental demonstrations of the proposed method and discuss the threats posed by the attack on power-saving mode based on the results. |
