Bluetooth Just Works: Security and Vulnerability
Mohamed Yanis Sadaoui, Sirine Hamza, Osman Salem, Ahmed Mehaoua · 2023
Bluetooth Low Energy (BLE) is widely applied in various gadgets and Internet of Things (IoT) packages through-out diverse fields which include healthcare, home automation, transportation, and agriculture. It evolves classic Bluetooth generation, permitting integration into aid-constrained gadgets that can operate for months, or even years, on an unmarried coin cell battery. To establish connections with peer gadgets, the bulk of BLE devices in the marketplace hire the “Just Works” pairing approach. This lightweight mode locations the onus of protection implementation on application builders and device producers. Unfortunately, marketplace pressures frequently sideline safety issues, leading to a plethora of inclined clever devices. In this paper, we observe the vulnerabilities related to the “Just Works” pairing in BLE. We behavior a case examination related to a smart mild bulb to intercept BLE communications between entities. Subsequently, we advocate an algorithm aimed at improving the safety of the “Just Works” pairing method.
