Comment on Commercial Flights Are Experiencing 'Unthinkable' GPS Attacks and Nobody Knows What to Do
SeriousBug@infosec.pub 7 months agoNope. And more importantly, it looks like nobody considered what might happen if the signal gets spoofed. The backup systems that are supposed to keep working if GPS breaks also break due to these spoofed signals.

GPS is encrypted, it’s just that the US military won’t share the encryption keys so the rest of us have to use the unencrypted channels. They’ve clearly thought about it and decided against making it public.

If they shared the encryption keys, then it wouldn’t be safe from spoofing anymore. The whole point of encryption is to not share the keys.
Also, before someone tries to point out PKI, the satellites don’t use PKI. So that’s not relevant. You can’t share the current keys without jeopardizing the system.

PKI? I assume you mean asymmetric encryption? That’s been available long before the GPS system was launched. Why do you think it isn’t relevant?

The military didn’t design it for civilian use. That’s really all there is to it.
