스마트 IoT 기기의 동작 검증을 위한 패킷 분석 프로그램

초록

Verifying the behavior of smart Iot devices in the ubiquitous era is emerging as an important issue. Blackbox testing is required to handle exceptions or errors that are difficult to detect in typical test environments, but may occur in real-world use cases. In this paper, we present Packet Analyzer, a program that performs blackbox testing on ZigBee and Bluetooth Low Energy (BLE), which are protocols mainly used in communication among Iot devices. Packet Analyzer collects ZigBee and BLE packets, beacon packets, IoT hub logs and smartphone logs. Then it analyzes test commands based on collected packets and logs to make decisions for each test command. Our evaluation on real-world smart IoT devices shows that Packet Analyzer can make correct decisions on various test commands.
