: End-to-End Security in RFC 3588

Hi All,

In Section 2.9, End-to-End Security Framework,  RFC 3588 mentions:

   End-to-end security services include confidentiality and message
   origin authentication.  These services are provided by supporting AVP
   integrity and confidentiality between two peers, communicating
   through agents.

   End-to-end security is provided via the End-to-End security
   extension, described in [AAACMS].  The circumstances requiring the
   use of end-to-end security are determined by policy on each of the
   peers. Security policies, which are not the subject of
   standardization, may be applied by next hop Diameter peer or by
   destination realm.  For example, where TLS or IPsec transmission-
   level security is sufficient, there may be no need for end-to-end
   security.

I could not find [AAACMS] either as an Internet-Draft or an RFC.  Has this 
work been completed?  And does anyone have the RFC number?  Or, has this 
work been abandoned? 

Thanks for any help.

Best Regards,
Timothy Smith
