Hi, all:

We have made a new version of the PCP Auth document according to the comments we got since the last IETF meeting. The main changes include:

1)Addressed comments given by Dave Thaler in http://research.microsoft.com/en-us/um/people/dthaler/draft-ietf-pcp-authentication-06.pdf
2)It was decided in the PCP WG meeting that PA-acknowledgement will be sent if response cannot be generated immediately
3)Added that EAP-TEAP SHOULD be supported.
4)Removed traffic key and used transport key throughout the specification.
5Add discussions about ID indicator matching
6)Add a new type of error message for downgrade attacks.
7) Give clear definition of PA messages and Com PCP messages

So, could you please take a look at the draft and let us know if there is any additional comments?

Happy new year!

Cheers

Dacheng

> Abstract:
>    An IPv4 or IPv6 host can use the Port Control Protocol (PCP) to
>    flexibly manage the IP address and port mapping information on
>    Network Address Translators (NATs) or firewalls, to facilitate
>    communication with remote hosts.  However, the un-controlled
>    generation or deletion of IP address mappings on such network devices
>    may cause security risks and should be avoided.  In some cases the
>    client may need to prove that it is authorized to modify, create or
>    delete PCP mappings.  This document describes an in-band
>    authentication mechanism for PCP that can be used in those cases.
>    The Extensible Authentication Protocol (EAP) is used to perform
>    authentication between PCP devices.
