In this paper, we introduce a security vulnerability of Bluetooth Low Energy(BLE) and propose an improved security method to solve it. BLE is used to transmit and receive data between nodes such as sensors, wearable devices in the Internet of Things (IoT) environment. However, there is a possibility that an encryption key for communicating between nodes is cracked because of the security vulnerability of BLE. The security vulnerability of BLE is that the length of the Temporary Key (TK) to… CONTINUE READING
