Abstract
A mobile communication system includes a central processing unit coupled to a memory storing instructions for executing a User Equipment (UE) implemented by a transceiver and a controller that supports Proximity Services (ProSe), and a ProSe Function that supports the ProSe and communicates with the UE via a PC3 interface. The UE sends a message for a discovery to the ProSe Function via the PC3. The ProSe Function directly sends security information to the UE via the PC3. The UE directly sends a protected message to another UE on a PC5 interface using a key based on the security information.
