IoT Device Recognition Framework Based on Network Protocol Keyword Query.

The boost of 5G technology has brought IoT with enhanced feasibility, it is predictable to have a dramatically increased number of the IoT devices with Internet access. However, there will be certain numbers of devices that are extremely vulnerable, particularly with low level of security coding built in. Hackers might have a greater chance to launch DDoS attack. Therefore, identifiable IoT devices linked to the network security vulnerability database might mitigate the risks contributing to a safer cyberspace. This is of great significance to the security of the entire cyberspace. This paper proposes an IoT device identification technology based on network protocol keyword query. Firstly, the traffic packets sent by the IoT device are collected in real time. Then the traffic data carried by different network protocols is extracted by parsing traffic packets. Secondly, the traffic data is filtered and converted into identifiable information related to the identification attribute of the IoT device. Finally, with the search engine of the major Internet of Things e-commerce website, the information about the IoT device is obtained by inputting the protocol keyword.
