Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a system and method for key refresh in Authentication and Key Management for Applications (AKMA). The proposed method is to support KAKMA refresh by requesting the refreshing parameters from the network once the KAF is about to expire. Further, the proposed method is to support KAF refresh by requesting the refreshing parameters from the network once the KAF is about to expire. Further the proposed method uses certain mechanisms to provide the refresh parameter to the AUSF, AAnF and the UE as a part of AKMA Refresh procedure or as a part of UPU procedure. Further, the proposed method supports AKMA key refresh with limited impacts on AKMA services in 5G system. Furthermore, the proposed method is used to support a mechanism to address the Key synchronisation issue at a User Equipment (UE) side, AF and at the network side.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Methods and systems for generating/deriving CU-UP security keys for disaggregated gNB architecture are described herein. A UE/gNB can inform the gNB/UE about the capability of the UE/gNB to derive CU-UP security keys. CU-UP security keys comprise an integrity protection key and a ciphering key. The gNB derives an integrity protection key and a ciphering key upon determining that the UE supports derivation of the CU-UP security keys or the UE has capability to derive CU-UP security keys. The integrity protection key protects the integrity of data, in a DRB, traversing through a CU-UP. The ciphering key encrypts the data, in the DRB, traversing through the CU-UP. The gNB sends RRC connection reconfiguration messages, which include multiple parameters. The UE derives an integrity protection key and a ciphering key, for each DRB, based on the plurality of parameters, for protecting the integrity of the data and encrypting the data.

Abstract: The present disclosure relates to a pre-5G or 5G communication system to support higher data rates beyond 4G communication system such as LTE. The present disclosure enables the 3GPP system to protect the broadcasted unique UAV identities for a secured UAV communication. In remote identification process, the UAVs send the messages with flight information to the receiving party (i.e., UTM/USS, a TPAE or another UAV). Also, there are use cases on local broadcast of UAV identities for remote identification and tracking purposes. The present disclosure renders a mechanism that only the authorized personnel is able to decode the received broadcasting ID from the initiating UAV. The present disclosure protects unique UAV identities broadcasted so that, the fake UAV or unauthorized personnel cannot use the broadcasted ID for certain attacks such as impersonation of genuine UAV, tracking of the UAV and so on.

Abstract: Embodiments herein relates to preventing UE from bidding down to restricted RAT type. The method includes determining, by network apparatus, restricted RAT types based on a network policy associated with network operator and subscription data. The RAT types can be a 5G, 4G, 3G, and 2G. Further, the method includes transmitting RAT restriction information in signalling message or configuration message to indicate the restricted RAT types to the UE to prevent the UE camping on to the restricted RAT types.
