Abstract
Methods and system for simplified Protocol for Carrying Authentication for Network Access (sPANA) are disclosed. In the broadband architecture such as Broadband forum or WiMAX forum, a Network Access server (NAS) is one IP hop away from a user. Therefore, it is possible to relax the need in PANA to obtain an IP address prior to authentication. A PANA client (PaC) may use an unspecified IP address (e.g. 0.0.0.0 in TPv4) as a source address for authentication. A PANA Authentication Agent (PAA) may use an IP broadcast address as a network layer destination address (e.g. 0xffffffff). The present invention defines PANA Attribute-Value Pairs (AVPs) and procedures that allow a Challenge-Handshake Authentication Protocol (CHAP) exchange to occur in PANA. The PANA CHAP support may facilitate smooth migration from Point-to-Point Protocol (PPP) sessions to IP sessions in a DSL Broadband network environment. The sPANA can be desirably compatible with the PANA.
