Abstract
A method of performing authentication and authorization in Proximity based Service (ProSe) communication by a requesting device (31) which sends a request of a communication and a receiving device (32) which receives the request from the requesting device (31) and (32), the method including deriving session keys Kpc and Kpi from an unique key Kp at the requesting and receiving devices (31) and (32), using the session keys Kpc and Kpi for ProSe communication setup and direct communication between the requesting and receiving devices (31) and (32), starting the direct communication with the requesting and receiving devices (31) and (32). The key Kpc is confidentiality key and the key Kpi is integrity protection key.

A UE (User Equipment) for one-to-many direct communication, the UE comprising:
- at least one processor;
- and
- at least one memory coupled to the at least one processor, the memory storing instructions that, when executed by the at least one processor, cause the at least one processor to:
- receive a message including a group key from a network node if the UE is verified by the network node successfully,
- derive a first key and a second key from the group key, and
- perform the one-to-many direct communication protected by the first key and second key with other UEs.
