2. Terminology
This document uses
terminology defined in [RFC3748], [RFC5295],
[RFC5296], and [RFC4072]. "Root key" (RK) or
"bootstrapping material" refer to the rRK or rDSRK
derived from an EMSK, depending on the location of the ER server in home or foreign domain. We note in this document
ERP/DER a Diameter-EAP-Request command with
the Application Id set to Diameter ERP application. On the same model, we use ERP/DEA, EAP/DER and EAP/DEA. [Qin]: what does the same model mean? how about saying: " We note in this document ERP/DER *refer to* a Diameter-EAP-Request Command with the Application Id set to Diameter ERP application. *Similarly*, we use ERP/DEA, EAP/DER and EAP/DEA " [Qin] I am wondering how EAP/DER and ERP/DER can be used in the same one roundtrip exhange between the authenticator, ER server and home EAP server. In my understanding, when to use ERP/DER and when to use EAP/DER depends on the deployment scenario and bootstrapping mode. e.g., in implicit bootstrapping mode, we use EAP/DER, in explicit bootstraping mode, we use ERP/DER? another example when home EAP server does not support ERP and ER server support EAP, in this case, EAP/DER and EAP/DEA can be used between ER server with EAP proxy function support and home EAP server. Am I right? |
