name: KgNB
full_form: Key generated during Next Generation Node B key derivation
context: This input string is used when the IAB-node and the IAB-donor derive KIAB (PSK) for establishment of secure F1 interface. The following parameters shall be used to form the input S to the KDF: - FC = 0x83, - P0 = IAB-donor-CU IP address, - L0 = length of IAB-donor-CU IP address, - P1 = IAB-node DU IP address, - L1 = length of IAB-node DU IP address. The input key KEY shall be KgNB, if the key KgNB is in possession of the IAB-UE functionality in the IAB-node and in the IAB-donor-CU (also when acts as MN for NR-DC scenario), after the IAB-UE setup procedure (Phase-1). The input key KEY shall be S-KgNB, if the key S-KgNB is in possession of the IAB-UE functionality in the IAB-node and in the IAB-donor-CU (acts as a SN for EN-DC scenario), after dual connectivity procedure. The input key KEY shall be KSN, if the key KSN is in possession of the IAB-UE functionality in the IAB-node and in the IAB-donor-CU (acts as a SN for NR-DC scenario), after dual connectivity procedure. For P0, in case of CP-UP separation of IAB-donor-CU, - P0 shall be set to IAB-donor-CU-CP IP address for deriving KIAB-CU-CP. - P0 shall be set to IAB-donor-CU-UP IP address for deriving KIAB-CU-UP. The entire output of the KDF (256 bits) is used as the KIAB or KIAB-CU-CP or KIAB-CU-UP..
description: KgNB refers to a key generated during the Next Generation Node B key derivation process. This parameter plays a crucial role in establishing secure F1 interfaces between IAB-nodes and IAB-donors, particularly in scenarios involving Integrated Access and Backhaul (IAB) functionality. The KgNB is utilized as an input key for deriving KIAB (Pre-Shared Key), which ensures the confidentiality and integrity of communications over the F1 interface.
explanation: KgNB is classified as a Parameter because it serves as a specific value used in the derivation process of another key, KIAB. Its role is pivotal in securing the communication between IAB nodes and donors, fitting within the broader context of 3GPP's security specifications for next-generation networks.
