PhyLeave: Physical layer key based interleaving for secure wireless communication

Overview

Executive Statement:

A revolutionary approach to securing wireless communications through physical layer interleaving and encryption, significantly enhancing security with minimal overhead.

Description:

The technology introduces PhyLeave and PilotCrypt, innovative methods to secure wireless communications at the physical layer. By using a dynamic key-based interleaving system, these methods provide robust security measures that are difficult for adversaries to breach. PhyLeave focuses on the flexible interleaving of data to obfuscate packet transmissions, while PilotCrypt rearranges data-bearing and pilot tone sub-carriers in OFDM systems. Both techniques are designed to ensure security even when traditional software encryption keys are compromised, utilizing low hardware overhead and allowing rapid key updates.
