Physical Gate based Preamble Obfuscation for Securing Wireless Communication

Overview

This invention is a technique for securing wireless communication between a transmitter and receiver by obfuscating the preamble data of the baseband signal at the physical layer. The obfuscation is achieved using unique obfuscation keys generated independently at the transmitter and receiver based on their reciprocal channel characteristics. This method aims to prevent eavesdropping, reactive jamming, and other malicious attacks on wireless transmissions.
