Bluetooth Low Energy Mesh Networks
Muhammad Rizwan Ghori, Tat‐Chee Wan · 2020
Bluetooth Low Energy (BLE) Mesh Networks enable flexible and reliable communications for low-power Internet of Things (IoT) devices. Most BLE-based mesh protocols are implemented as overlays on top of the standard Bluetooth star topologies while using piconets and scatternets. Nonetheless, mesh topology support has increased the vulnerability of BLE to security threats, since a larger number of devices can participate in a BLE Mesh network. To address these concerns, BLE version 5 enhanced existing BLE security features to deal with various authenticity, integrity, and confidentiality issues. Despite of the BLE version 5 security enhancements, viable IDS solutions for BLE Mesh networks remain a nascent research area.
