Chaotic-Map Key Streaming

Chaotic-Map Key Streaming for eVTOL Authentication

Undergraduate research · University of Southern Mississippi · 2024 – present

An FPGA authentication scheme for eVTOL drones built on Chebyshev chaotic maps and SHA in VHDL-2019. Keys are generated from a shared seed on demand rather than stored, so a fleet’s key material never sits on the aircraft.

Ground stations and pilot consoles share one look-up table; registration runs through challenge and response.
