Section: 9.10 Security mechanisms for the interface between W-5GAN and 5GC
Content: The W-AGF function in Wireline 5G Access network (W-5GAN) terminates the following interfaces: - N2 interface between the W-5GAN and the AMF. -N3 interface between the W-5GAN and the UPF. The security of the N2 interface between the W-5GAN and the AMF is as defined in clause 9.2 of the present document. The security of the N3 interface between the W-5GAN and the UPF is as defined in clause 9.3 of the present document. On the W-AGF side a SEG may be used to terminate the IPsec tunnels. NOTE: Clauses 9.2 and 9.3 require that the N2 and N3 interfaces are integrity, confidentiality, and replay protected. The same protection can be achieved by placing the AGF in the same trust domain as the AMF and the SMF.
