Abstract

The invention relates to a radio frequency fingerprint identity authentication method based on immunity. The method comprises the following steps: firstly, acquiring WiFi signal data and preprocessing the WiFi signal data; then, radio frequency fingerprint extraction is carried out based on the preprocessed WiFi signal data, and a radio frequency fingerprint vector is obtained; then, determining a variable radius autologous body based on the radio frequency fingerprint vector; then, determining a mature detector set by adopting an evolution-based detector generation method; and finally, adopting the mature detector set to detect the variable radius autologous body to obtain an identity authentication result. A safe and lightweight identity authentication method is provided, consumption of computing resources is reduced, and the accuracy of identity authentication is improved.
