At the very same time it is trivial to update the drones of today to use a secure mutual authentication mechanism which the "drone defender" cannot break into. So, even if there is a spectrum DoS (which might be illegal to do for anyone apart from law enforcement) its not that the defender will take over the drone.
This is a cat n mouse game where the drone creator always has an advantage.
- ryandamm 10y agoYeah, but GPS isn't a handshake, and most commodity drones rely on it. You can't take it over, but you can probably blind it.
- WalterSear 10y agoIran claims to have captured drones by spoofing the GPS.
- mhowland 10y agoIt's been spoofable (and jamable) for some time...but serious PIA to do and a huge FCC no-no as it's tough to focus. http://news.utexas.edu/2013/07/29/ut-austin-researchers-successfully-spoof-an-80-million-yacht-at-sea http://news.utexas.edu/2013/07/29/ut-austin-researchers-succ...
- run4yourlives2 10y agoDo you really need GPS to tell the drone, "Remember your flight control inputs and reverse them on loss of signal?" I'm sure it's not trivial, but drone defence based completely on signal interception seems straightforward to defeat.
