name: KAMF
full_form: Key Authentication Management Field
context: Derivation of KAMF' from KAMF during mobility shall use the following input parameters. - FC = 0x72 - P0 = DIRECTION - L0 = length of DIRECTION (i.e. 0x00 0x01) - P1 = COUNT, - L1 = length of COUNT (i.e. 0x00 0x04) The input key KEY shall be KAMF. When KAMF' is derived in handover, DIRECTION shall be 0x01 and COUNT shall be the downlink NAS COUNT of the 3GPP access. When KAMF' is derived in idle mode mobility (i.e., mobility registration update), DIRECTION shall be 0x00 and COUNT shall be the uplink NAS COUNT of the 3GPP access used in the Registration Request.
description: The Key Authentication Management Field (KAMF) is a parameter utilized in the derivation process of KAMF' during mobility events, such as handovers and idle mode mobility registrations. It serves as an input key for this derivation, ensuring secure authentication management within the network.
explanation: KAMF is classified as a Parameter because it is used as an input value in a specific algorithmic process (derivation of KAMF') to manage authentication keys during different types of mobility events in the 3GPP access network.
