Hi Sri, I do believe we need to specify a default security mechanism for the MAG/LMA signaling messages. And for this purpose, IPsec is a good choice. So IMO it is required that we state "Proxy MIP6 signaling messages between the MAG and LMA MUST be secured by the use of an IPsec SA between the two entities". I think this does not limit the ability to adopt alternative security solutions in the future. -Raj On 9/7/07 12:10 PM, "ext Sri Gundavelli" <sgundave@cisco.com> wrote: > Hi Julien, > > > >> -----Original Message----- >> From: julien laganier [mailto:julien.laganier@gmail.com] On >> Behalf Of Julien Laganier >> Sent: Friday, September 07, 2007 5:29 AM >> To: netlmm@ietf.org >> Cc: Sri Gundavelli; 'Alper Yegin' >> Subject: Re: [netlmm] Issue: Auth Option support >> >> Hi Sri, >> >> On Thursday 06 September 2007, Sri Gundavelli wrote: >>> I'm confused, should the draft say >>> >>> "Both LMA and MAG MUST implement IPsec" and >>> "all the signaling messages SHOULD be protected using IPSec". >>> >>> Will this ok, when reviewed by the security folks ? >>> >>> or mandate IPsec for this specification and let other draft >>> relax this in the presence of an alternative approach ? >>> >>> Please comment. >> >> Somehow, "MUST implement" and "SHOULD use" together seems a bit >> tautologic. >> >> To me "SHOULD use" is sufficient since it covers both of the two >> possibles cases: >> >> - deployment follows the SHOULD recommendation, it uses IPsec >> to protect >> PMIPv6, in which case it supports it, since it's using it :), or >> >> - deployment ignores the SHOULD recommendation, does not uses >> IPSec, in >> which case it is useless to implement it since it's not used... >> >> I'd prefer having "MUST protect integrity of signalling messages, and >> SHOULD use IPsec ESP to protect integrity of those messages". >> We might >> also add "MAY use IPsec AH". >> > > > I agree.
