Apparatus System And Method For Secure Direct Communcation In Proximity Based Services
Abstract: In order for effectively ensuring security for direct communication in ProSe a ProSe Function (20) acquires from a 3rd party root keys for each of UEs (10_1 10_m) 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 (10_1 10_m). Each of the UEs (10_1 10_m) 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.
