name: KASME
full_form: Key Agreement Shared Master Encryption
context: This input string is used when there is a need to derive KASME' from KAMF during mapping of security contexts from 5G to EPS at handovers. The following input parameters shall be used. - FC = 0x74 - P0 = NAS Downlink COUNT value - L0 = length of NAS Downlink COUNT value (i.e. 0x00 0x04) The input key KEY shall be KAMF.
description: Key Agreement Shared Master Encryption (KASME) is a Key  used in the context of handovers between 5G and EPS networks. It involves deriving KASME from Key Agreement Master Function (KAMF) during the mapping of security contexts. The process utilizes specific input parameters, including a fixed value (FC = 0x74), the NAS Downlink COUNT value (P0), its length (L0 = 0x00 0x04), and the input key KEY which is KAMF. This protocol ensures secure encryption and key agreement during handover procedures.
explanation: KASME is classified as a Parameter because it outlines a specific set of rules and steps for deriving keys and ensuring security during handovers between different network systems, adhering to the detailed specifications provided in the context.
