name: SEAF
full_form: Security Edge Protection Proxy Application Function
context: The EAP framework is specified in RFC 3748 [27]. It defines the following roles: peer, pass-through authenticator and back-end authentication server. The back-end authentication server acts as the EAP server, which terminates the EAP authentication method with the peer. In the 5G system, the EAP framework is supported in the following way: - The UE takes the role of the peer. - The SEAF takes the role of pass-through authenticator. - The AUSF takes the role of the backend authentication server.
description: The Security Edge Protection Proxy Application Function (SEAF) is a network function in the 5G system that acts as a pass-through authenticator within the EAP framework. It plays a crucial role in facilitating authentication processes between the User Equipment (UE) and the Authentication Server Function (AUSF), ensuring secure access to network resources.
explanation: SEAF is classified as a Network Function because it serves as an intermediary component in the authentication process, bridging the UE with the AUSF. This role aligns with the 3GPP's specifications for security architecture and procedures in the 5G system.
