Bluetooth Low Energy has established itself as one of the central protocols of the Internet of Things. Its many features (mobility, low energy consumption) make it an attractive protocol for smart devices. However, numerous critical vulnerabilities affecting BLE have been made public in recent years, some of which are linked to the protocol's design itself. The impossibility of correcting these vulnerabilities without affecting the specification requires the development of effective intrusion detection systems, enabling the detection and prevention of these threats. Unfortunately, the protocol relies on peer-to-peer communications and introduces many complex and dynamic mechanisms (e.g., channel hopping), making monitoring complex, costly and limited. Existing intrusion detection approaches lack flexibility, are limited in scope and introduce high deployment costs.
