Abstract
We propose a lighting control system based on a near-field version of Bluetooth Low Energy (BLE) Technology, called NFB, and an access control protocol to enhance security. At the hardware level, we reduce the RF power of the BLE transceiver to that comparable to Near Field Communi- cation (NFC) so that it can mimic the convenient contactless-style authentication in NFC ID cards. While the reduced RF power of NFB makes it more difficult for attackers to snoop compared to stan- dard BLE, we add another encryption layer to further strengthen the security of NFB beyond AES128 crypto co-processor built into BLE today. Experimental results show that our proposed scheme to provide strong security for protecting future smart home systems.
