| Popis: | 104 As Bluetooth Low Energy (BLE) has become a de-facto standard for Internet of Things (IoT) devices, users can control nearby IoT devices with personal smartphones via BLE. To prevent unauthorized users from accessing IoT devices, users may need to pair with IoT devices for the devices to authenticate the users and to establish security channels between the users and the devices. Obviously, if users wish to access many BLE devices, the users may need to waste time on pairing with each device independently. In light of this, this study proposes a means for users to communicate nearby BLE-based IoT devices via gateways. This study provides a means to mapping BLE commands on CoAP. Therefore, users can use their smartphones to connect to gateways with WiFi and send CoAP requests to gateways. The gateways play the role as mediators to send the requests to associated devices with BLE and collect responses from the devices. After transforming the responses into CoAP format, and forward the responses to the user smartphones. Moreover, while device managers can centrally control access permissions of the devices in gateways, this study can also reduce security management costs. Therefore, this study can hopefully contribute to enable users to access nearby IoT devices conveniently and securely. |
