[Abstract]:Aiming at the problem that low power Bluetooth is vulnerable to flooding attack, a connection authentication model is proposed. Based on this model, a low power Bluetooth flooding attack defense scheme is designed. Combined with the characteristics of HMAC (high speed of hash-based message authentication code) operation and strong synchronization of Bluetooth communication), a detection module is designed to judge the communication status, and a connection request authentication protocol is designed by means of challenge response. Two-way authentication of master-slave devices is carried out before the Bluetooth protocol is run, and attack packets are filtered out to ensure the security of low-power Bluetooth connection establishment. The security analysis and experimental results show that the proposed scheme can effectively protect against flooding attack and has less storage and computing overhead, so it is suitable for low power Bluetooth.
