Diameter IKEv2 SK: Using Shared Keys to Support Interaction between IKEv2 Servers and Diameter Servers

The Internet Key Exchange Protocol version 2 (IKEv2) is a component ofthe IPsec architecture and is used to perform mutual authentication aswell as to establish and to maintain IPsec Security Associations (SAs)between the respective parties. IKEv2 supports several differentauthentication mechanisms, such as the Extensible AuthenticationProtocol (EAP), certificates, and Shared Key (SK). Diameterinterworking for Mobile IPv6 between the Home Agent (HA), as aDiameter client, and the Diameter server has been specified. However,that specification focused on the usage of EAP and did not includesupport for SK-based authentication available with IKEv2. Thisdocument specifies the IKEv2-server-to-Diameter-server communicationwhen the IKEv2 peer authenticates using IKEv2 with SK. [STANDARDS-TRACK]
