Symmetric Encryption Key Generation Using Wireless Physical Layer Information Without Sharing Any Information Pertinent To The Key

Overview

Executive Statement:

An innovative technology that generates symmetric encryption keys from the wireless physical layer, enhancing security in wireless communications.

Description:

This technology leverages the randomness inherent in the physical (PHY) layer of wireless communication channels to generate symmetric encryption keys for secure communication between a transmitter and a receiver. By utilizing channel state information (CSI) and the unique characteristics of reconfigurable antennas, the algorithm produces highly randomized encryption keys without the need for traditional pseudorandom number generators or initialization vectors. This method significantly reduces the risk of secure information leakage during the key establishment phase, ensuring a more secure wireless communication environment.
