Communication is Verification: IoT Identifier System Using Device Fingerprints

With the gradual development of the Internet of Things, people rely more and more on the Internet of Things devices to assist their daily lives. The permissions of IoT devices make it easy for them to rescue or destroy our lives. This paper proposes a new scalable IoT security framework (ISDF), which uses the unforgeable physical layer characteristics of IoT devices as the verification basis to identify illegal devices. This framework combined with the identifier generation algorithm to generate a unique trusted identifier. Under the verification of more than a dozen devices such as bluetooth, wifi, and voice, the identifiers we generate have high robustness and stability, the accuracy of verification is more than 93%. Compared with existing solutions, our framework has the advantages of supporting multimodality and high verification success rate.
