Comment on Commercial Flights Are Experiencing 'Unthinkable' GPS Attacks and Nobody Knows What to Do
grandkaiser@lemmy.world 11 months agoIf 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.

I’m the commenter you originally replied to. If the US military wanted unspoofable GPS available to everyone then it would be available to everyone. They only want the public to have unencrypted GPS, so that’s all we get.

The military is as concerned with civilian gps as much as they are with anything else that isn’t military-related: not their issue to solve. They won’t stop anyone from using encrypted gps. They really won’t. The only branch on the us that actively tries to prevent public encryption is the NSA. (Even then, they wouldn’t block something like gps). For the record, I’m a security engineer, previously worked for the DOD, and used to work in satcom.
