碩士 === 國立臺灣科技大學 === 資訊管理系 === 104 === The smart phone has become so popular that we can be certain almost everyone has at least one smart phone. Most smart phones right now support the Bluetooth Low Energy (BLE) protocol to exchange data. Therefore, Internet of Things (IoT) applications usually use BLE for device communication. Devices can bind with each other to exchange session keys for secure communication. However, there are vulnerabilities in Legacy BLE binding schemes. The vulnerabilities are addressed in new versions of BLE protocols, but many current devices do not support new versions of BLE protocols. In light of this, this thesis proposes a secure layer for BLE communication. Our secure layer relies on BLE GATT services to provide applications with standard interfaces for authentication and security channel establishing between BLE-based devices. As a result, the secure layer can address the vulnerabilities without replacing the existing system, and also improve the security of IoT applications.
