name: TIMF
full_form: Temporary Identity Management Function
context: - The VCF (V2X Control Function) is mainly responsible for authentication and authorization V-UE through HSS on user plane. - The TIMF (Temporary ID Management Function) is mainly responsible for distribute the temporary IDs and credentials to V-UE and V2X data source accountability. - The TIMF could be deployed as one network element with VCF, and they share the same interface V3. - V2X CA could be setup as multilayer CA system. No matter how to structure the V2X CA in real deployment, they could be simplified as a logical V2X CA in the security architecture diagram. - There are two new reference points introduced: - V7: This is the reference points between the TIMF and V2X CA/V2X KMS. Since the interworking messages on how to enrolment a key pairs from a V2X KMS or digital certificates from V2X CA are relied on existing and mature commercial products in industry, it should align with those existing protocols. - It is up to V2X Service Operator to choice V2X KMS or V2X CA. But the
description: The Temporary Identity Management Function (TIMF) is a network element responsible for distributing temporary IDs and credentials to Vehicle-to-Everything User Equipment (V-UE) and V2X data sources, ensuring accountability in V2X communications.
explanation: Based on the context from 3GPP TS 33.885, TIMF is classified as a Network Function due to its role in managing temporary identities and credentials within the network, interacting with other network elements like VCF and V2X CA/KMS.
