Title:
METHODS AND SYSTEMS FOR ESTABLISHING SECURE COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/019627
Kind Code:
A1
Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Embodiments herein disclose methods for establishing secure communication in a wireless communication network (3000) by an AUSF entity (400). The method includes receiving a key request message from a remote UE (100a) through an AMF entity (500). Further, the method includes acquiring one of the SUPI of the remote UE (100a) and a REAR ID associated with the SUPI of the remote UE (100a). Further, the method includes generating a rear key for remote UE (100a) communication via a UE-to-network relay. The REAR key is used for deriving a first ProSe key. Further, the method includes sending a key response message to the remote UE (100a) for establishing secure communication, where the key response message includes the generated REAR key, the REAR ID and at least one of a relay UE ID and a temporary ID of a relay.
