    But if they had authentication you would know that the message doesn’t come from a legitimate satélite.

      If their isn’t then there’s a big problem with implementing that now, which would require a retrofit of every single GPS system currently in use and likely a replacement of all GPS satellites

      Edit: I’m slightly mistaken, the military uses encryption but they don’t have that open for public use.

      you can’t have authentication in a one way system. satellites send days, planes receive it, but never send anything.

            Playing with semantics a little, it can be thought of as the satellite authenticating with the client using the signature as password.

            That’s not how PKI works?

            Unless you know how digital signatures work better than me

            You can’t copy a signature, since it is different every time the signed content is different. You need to have the correct key in order to make a valid signature.

            If you’ve figured out how to do that, a lot of governments would pay you a lot of money for your solution
