Abstract

A computer-implemented method for authenticating an access point attempting to access a wireless network is presented. The computer-implemented method includes receiving an authentication challenge from the access point, analyzing the authentication challenge at a wireless node by using an optical chaos generation module having an optical section and a radio frequency (RF) section to facilitate reproducibility, unpredictability, and unclonability of challenge-response pairs, and transmitting an authentication response to the access point.
