Multicast with VPN

2001-04-04 Thread dark dark

hi,
Does any one have any idea if we can use IPSec with
multicast address. In RFC-2401 I have read 
"In principle, the Destination Address may be a
unicast address, an IP broadcast address, or a
multicast group address.  However, IPsec SA management
mechanisms currently are defined only for unicast
SAs." 
they have explained how to use multicast address in
IPSec SA, in principle.
but this RFC was published in 1998. nothing changed
till now?
thanks

 * RFC 3093 on Firewall Enhancement Protocol
   http://www.faqs.org/rfcs/rfc3093.html
 
   Internet Transparency via the end-to-end architecture of the Internet
   has allowed vast innovation of new technologies and services [1].
   However, recent developments in Firewall technology have altered this 
   model and have been shown to inhibit innovation.  We propose the
   Firewall Enhancement Protocol (FEP) to allow innovation, without
   violating the security model of a Firewall.  With no cooperation from
   a firewall operator, the FEP allows ANY application to traverse a
   Firewall.  Our methodology is to layer any application layer
   Transmission Control Protocol/User Datagram Protocol (TCP/UDP) packets
   over the HyperText Transfer Protocol (HTTP) protocol, since HTTP
   packets are typically able to transit Firewalls.  

I was disappointed in this RFC, since it doesn't actually work;
typically the user who is trapped on the inside of the firewall only
can initial HTTP connections, and so you have to play some polling
games (and ideally encapsulate multiple packets as part of the HTTP
GET response for efficiency's sake) in order to process packets from
the outside of the firewall making it back into inside-firewall user.

Of course, in order to be practical you'd also want to add some
encryption plus some varying steganography so that you can evade
firewall vendors trying to detect and prevent such http tunnelling
requests.

I had talked about this with a few folks a year or two ago as a
possible April 1st RFC, but we had wanted to back it up with real,
live running code which demonstrated something which could actually
work.  ah, well, so many interesting projects, so little time

Hi,

Yes, IPsec allows for a Class D address (multicast)
with no change.  As far as a multicast receiver is
concerned, the packet will be an IPsec packet that
will be treated in the usual IPsec manner.
The IPsec indexing triplet SPI, DestAddr, ProtocolType
remains the same.

The problem is that IKE is a pairwise key/SA establishment
protocol, which cannot be used as is within a group/multicast
context.

The MSEC WG is working precisely on this topic.
Their drafts can be found on www SecureMulticast.org.

cheers,

thomas

 In doing this, you leave the ISOC copyright there, which asserts that the
 ISOC has your permission to publish the document in the RFC archive, and
 protects it from unauthorized modifications or claims. Doing so, according
 to our counsel '...is as close to a "contribution to the public" that we
 can get'.

Dear honest lawyers, counsels, et. al.:

May I know, how close to a "contribution to the public"; the GNU Free 
Documentation License is? See also

Not very.  At least it's not as viral as the GPL, and they don't
require you (in section 3) to *personally* distribute sources for
3 years if you ship binaries of GPL programs (which irked me no end
when building installable packages for AIX - even though I made *no*
source changes, I asked (and was told) that just pointing at ftp.gnu.org
for the source wasn't acceptable).  You only need take "prudent steps"
for one year to ensure the place you point people stays there.

Remember that the GNU crowd has an agenda, and their licensing is
written to enforce that agenda.

 Not very.

From the preamble:

  "The purpose of this License is to make a manual, textbook, or 
   other written document "free" in the sense of freedom: to assure 
   everyone the effective freedom to copy and redistribute it, with or 
   without modifying it, either commercially or noncommercially.  
   Secondarily, this License preserves for the author and publisher 
   a way to get credit for their work, while not being considered 
   responsible for modifications made by others."

I have no problem with that. However; since I am not a lawyer, I am
just wondering if there are hidden catches that I am not aware of.

 At least it's not as viral as the GPL, and they don't
 require you (in section 3) to *personally* distribute sources for

 for the source wasn't acceptable).  You only need take "prudent steps"
 for one year to ensure the place you point people stays there.

Section 3 of GPL http://gnux.vlsm.org/copyleft/gpl.txt has three
options, "a" (accompany with source code) , "b" (three years commitment
to distribute), and "c" (providing pointers). So, what is the problem 
to choose one of them?
