Abstract
In order for effectively ensuring security for direct communication in ProSe, a ProSe Function acquires from a 3rd party root keys for each of UEs to derive a pair of session keys for securely conducting direct communication with different UEs, and distributes the acquired root keys to each of the UEs. Each of the UEs derives the session keys by using one of the distributed root keys. Moreover, a plurality of UEs, which form a communication system, and are allowed to conduct direct communication with each other when the UEs are in proximity to each other, share public keys of the UEs therebetween through a node which supports the direct communication upon successfully registering the UEs with the node. Each of the UEs verifies at least a request for the direct communication by using one of the public keys.
