Then you need to define your protocol such that the client and server
engage in some sort of identification / authentication exchange when
Client: Who are you?
Server: I am PID 12345
Client: That's not who I was expecting, I'm going away!
Depending on how secure you need this to be, the exchange might
include some kind of cryptographic signature.
