10. AVP Occurrence Tables

The following tables present the AVPs used by NAS applications in NAS messages and specify in which Diameter messages they MAY or MAY NOT be present. [BASE] messages and AVPs are not described in this document. Note that AVPs that can only be present within a Grouped AVP are not represented in this table. The table uses the following symbols: 0 The AVP MUST NOT be present in the message. 0+ Zero or more instances of the AVP MAY be present in the message. 0-1 Zero or one instance of the AVP MAY be present in the message. 1 One instance of the AVP MUST be present in the message.

10.1. AA-Request/Answer AVP Table

11. IANA Considerations

This section provides guidance to the Internet Assigned Numbers Authority (IANA) regarding registration of values related to the Diameter protocol, in accordance with BCP 26 [IANAConsid]. This document defines values in the namespaces that have been created and defined in the Diameter Base [BASE]. The IANA Considerations section of that document details the assignment criteria. Values assigned in this document, or by future IANA action, must be coordinated within this shared namespace.

11.1. Command Codes

This specification assigns the value 265 from the Command Code namespace defined in [BASE]. See sections 3.1 and 3.2 for the assignment of the namespace in this specification.
ToP   noToC   RFC4005 - Page 78

11.2. AVP Codes

This specification assigns the values 363 - 366 and 400 - 408 from the AVP Code namespace defined in [BASE]. See sections 4 and 5 for the assignment of the namespace in this specification. Note that the values 363 - 366 are jointly, but consistently, assigned in [DiamMIP]. This document also creates one new namespace to be managed by IANA, as described in section 11.5. This specification also specifies the use of AVPs in the 0 - 255 range, which are defined in [RADIUSTypes]. These values are assigned by the policy in RFC 2865 section 6 [RADIUS] and are amended by RFC 3575 [RADIUSIANA].

11.3. Application Identifier

This specification uses the value one (1) in the Application Identifier namespace as assigned in [BASE]. See section 1.2 above for more information.

11.4. CHAP-Algorithm AVP Values

As defined in section 5.5, the CHAP-Algorithm AVP (AVP Code 403) uses the values of the "PPP AUTHENTICATION ALGORITHMS" namespace defined in [PPPCHAP].

11.5. Accounting-Auth-Method AVP Values

As defined in section 8.6, the Accounting-Auth-Method AVP (AVP Code 406) defines the values 1 - 5. All remaining values are available for assignment via IETF Consensus [IANA].

11.6. Origin-AAA-Protocol AVP Values

As defined in section 9.3.6, the Origin-AAA-Protocol AVP (AVP Code 408) defines the value 1. All remaining values are available for assignment with a "Specification Required" policy [IANAConsid].

12. Security Considerations

This document describes the extension of Diameter for the NAS application. The security considerations of the Diameter protocol itself have been discussed in [BASE]. Use of this application of Diameter MUST take into consideration the security issues and requirements of the Base protocol.
ToP   noToC   RFC4005 - Page 79
   This document does not contain a security protocol but does discuss
   how PPP authentication protocols can be carried within the Diameter
   protocol.  The PPP authentication protocols described are PAP and
   CHAP.

   The use of PAP SHOULD be discouraged, as it exposes users' passwords
   to possibly non-trusted entities.  However, PAP is also frequently
   used for use with One-Time Passwords, which do not expose a security
   risk.

   This document also describes how CHAP can be carried within the
   Diameter protocol, which is required for RADIUS backward
   compatibility.  The CHAP protocol, as used in a RADIUS environment,
   facilitates authentication replay attacks.

   The use of the EAP authentication protocols described in [DiamEAP]
   can offer better security, given a method suitable for the
   circumstances.
