SUMMARY:Ghosts in the Sky: Creating Phantom Aircraft with Mode-S Transpond

DESCRIPTION:Modern commercial aircraft constantly exchange information usi
 ng Mode-S transponders\, ADS-B broadcasts\, and TCAS collision avoidance m
 essages. These systems help keep aircraft safely separated\, but were desi
 gned before authenticated wireless communications became a security concer
 n.\n\nThis talk provides an introduction to the protocols that underpin ai
 rborne collision avoidance and investigates whether a phantom aircraft cou
 ld be introduced into the ACAS surveillance process through maliciously cr
 afted Mode-S transmissions.
