A method performed by a proximity service server. The method comprises generating a ProSe query code and a ProSe response code, sending at least the ProSe response code together with a first and a second discovery key to a first end device, and sending at least the first discovery key and the ProSe query code to a second end device, so that the second end device can securely discover the first end device over an air interface.
