Research on WiFi radio signal and MAC address mapping based on stream label

Abstract

Radio frequency signal information of a wireless terminal is based on inherent differences in hardware. It has uniqueness, time-invariance, independence and robustness. Therefore, it is also called the radio frequency fingerprint of the wireless device. It can be used for authentication and security access of the wireless terminal to enhance the security protection capability of wireless communication. However, the existing radio frequency fingerprint authentication technology is facing the problem of lack of corresponding identification when the radio frequency information acquisition module is linked with network management equipment. This paper studies a mapping technology between WiFi radio signals and MAC addresses based on GNU Radio stream labels, and establishes the corresponding relationship between the radio signal identification and the network layer identification by using the steps of signal collection, burst signal detection, burst location stream label creation, stream label transmission and update, and the mapping between burst signals and MAC addresses. The feasibility of this technology is verified by experiments.
