Internet of things (IoT) has been transforming our everyday life via many exciting applications such as smart home, connected healthcare, smart cities, to name but a few. Billions of devices are wirelessly connected, e.g., sensor nodes, fitbit, web cameras, etc. The majority of IoT devices are low cost with very limited computational resources and power supply. This has rendered an overlook on the security provision on IoT devices and unfortunately has resulted in numerous notorious IoT attacks, which have caused significant economic loss and compromised the IoT trustworthiness. The IoT security thus becomes the main bottleneck to promote secured and matured IoT applications.
The user identity authentication is essential to prevent malicious attackers from accessing the network. Conventional authentication is based on the device ID, such as MAC/IP addresses, which however can be tampered and spoofed easily. There is an emerging technique to employ the radio frequency fingerprinting (RFF) to authenticate IoT devices. Similar to the biometric fingerprints of human, radio devices also have their fingerprinting, which represents unique features of wireless transceivers resulted from manufacturing process. These features include oscillator frequency offset, I and Q mismatch, power amplifier non-linearity.
RFF can be exploited to authenticate the identities of wireless devices in a secure and lightweight manner. An authenticator first collects the RFF of the devices and stores them in a database. When the device wants to join the network again, the authenticator will extract the RFF of the candidate device, and compare it with the database to identify the device. This technique has attracted extensive research interests to classify wireless devices, such as WiFi, ZigBee, and LoRa.
There are still many fundamental research challenges to design a robust and reliable RFF identification system. This PhD project thus aims to obtain a better understanding on the RFF and enhance the classification performance using sophisticated artificial intelligence.
